I've heard rod knock. This isn't it. :o

I'm running Rotella 20-50 oil. I have the stock boost solenoid deleted (some people say it ticks). 1991 engine with original, small-hole lifters.

When I start the car up in a cold morning, the valvetrain clicks around for a while until it's warm. Then it usually goes away. However, when I start driving the car, I notice that around 1500-3000rpm, if I am using MODERATE throttle, I can hear ticking from the engine bay/firewall. Under no throttle or heavy throttle, I don't hear it at all. This is very repeatable; I can be cruising, and make the sound start at a very particular amount of low throttle, and make it dissappear by either letting off the throttle or giving it more throttle.

I suspect it might be that I'm just running really thick oil and that's what happens. It's the way that the sound only occurs during light throttle that confuses me.

Any ideas? Is there another solenoid or something that could be ticking? ]]> Engine - Turbo slo6 http://www.3si.org/forum/f35/engine-ticking-479687/ http://www.3si.org/forum/f35/91-stealth-rt-tt-need-mechanic-help-metro-detroit-area-479677/ Fri, 20 Nov 2009 20:23:17 GMT I have a 91 RT TT with 75k miles on it.

Just a quick question about the interchangeability of OEM engine mounts.
I'm replacing mine and have bought a set from IPS, which were listed as being for all models, 91-99. I noticed when they arrived that the front (t-belt side) mount was aluminum rather than steel, and didn't have the damper block that my existing one had. I didn't think too much of it at the time, and just figured it was a new superseding part.

Having recently done a check with CAPS, it looks like there are three different part numbers for that engine mount, and none of them seem to supersede to the others.
My car has a build date of Feb '91, and lists MB581692 as the correct mount.
From June '91, CAPS shows MB892448 - I'm not sure how this differs from the previous one, but I assume it is still steel.
From '94 on, the PN listed is MB870005. This part is the aluminium mount that I have.
I notice that 3SX have two different mounts listed, depending on year. I'm not sure what PN their 1st Gen one is.

Can anyone tell me if these parts are indeed interchangeable, or if I should swap the mount I have for the correct one as listed by Mitsi?
My preference is not to swap it - as I'd have to pay air freight to the US and back (I'm in New Zealand) to get the correct part. But I don't want to end up regretting my decision!

The Stealth Technical Manual has this to say (regarding the 1st gen mount):
"DOHC models have a dynamic damper on the top of the engine mount to cut out high frequency noise."
If I go ahead and use the Aluminum one will it be at the expense of increased engine noise? What did they change with the '94+ models to allow the use of the aluminum mount without a damper?

If anyone can provide some insight on this, that'd be great!

Kind regards,
Kenneth Wells

If I delete my stock boost solenoid what do I do with vac line (has white dashes) from the top of the boost solenoid that runs to the rear turbo. My second question is I know most people run the vac line from the y-pipe to the MBC, but I had read of someone using a different vac line such as one after the throttle body to his MBC and found that his turbo's spooled up a lot faster.

Basically my cars been at the dealership over 2 months for smoking stock turbo. Replaced it with a rebuilt pair of dr650Rs. It was still smoking from the front turbo. So I had Re-rebuilt the front dr650 by a very reputable turbo guy all brand new parts shipped direct from England. Took it to the dealership they reinstalled and say its still smoking. It is possible I guess maybe they didnt run it long enough to get the residual oil puddle out of the exhaust pipes, I hear it takes a couple weeks to burn out under normal driving.

The Turbo guy is reinspecting his work now. He swears he doesnt make mistakes, as he runs it up on a machine and inspects for leaks with a special violet oil and a blacklight, tests for boost pressure, balance, clearance issues , and spoolup before it leaves the shop. He seems to think the dealership are idiots and didnt prime the turbo with oil.

After 3 smoking turbos I think maybe it is an oil pressure problem or restriction downstream causing blow by into my exhaust. The dealership guys aren't much help with troubleshooting. They always blame it on me having aftermarket equipment. ]]> Engine - Turbo DC 95VR-4 http://www.3si.org/forum/f35/what-stock-oil-press-supposed-479504/ http://www.3si.org/forum/f35/nitrous-479471/ Wed, 18 Nov 2009 14:04:06 GMT thinking of getting and running a wet setup anypro's and cons....

It's a stock 9B, had little if no shaft play in it. So I primed the rear turbo (took out the ECI fuse, and turned the car over 2 times at about 7-10sec intervals. After that I started it, and with in probably 3-4 minutes I am getting a decent amount of smoke coming up from the turbo under the hood. It seems to be coming from all around the turbo, honestly I can't get my head close enough to see exactly, but I there's no oil or coolant under the car from the feed and return lines. I guess what I'm asking is this common with a turbo that has set for a while? So I let it idle longer (I let it idle for about 5min, then saw smoke so shut it off). What do you guys think??

While removing the rear plugs to use compressed air to check for bent valves, I noticed one of the plugs was actually loose.

My question is: Is the oil on it do to it being loose and blow-bye causing the buildup? The car doesn't smoke and ran very well before the belt issue. None of the valves are bent, or at least hold 90lbs of compressed air when checking that way. Like I said the plug was barely hand tight. See pic for reference.

Anyways, just wondering if this sounds more like lifter tick or a bearing, or something else. In my SOHC, I seem to be able to get rid of what little tick it has by revving the engine. In this car, though, it's pretty consistent.

I have been getting knock counts sometimes up to 28 (but never more than that, ever, it's like 28 is the ceiling) between 2500 and 3500 rpm when the engine deals with a bit of load. My wideband reads rich.

Just wondering if it's time to take it to my parents heated garage for the winter and install the engine I have sitting around.

Thanks for the help!

The idle seemed really rough when I went to buy the car, so I figured I'd do the 120k mi maintainence and see if that fixed any of the problems. After further inspection, I also replaced the vacuum lines (they weren't connected properly anyway). After all this, the car would still start, but it was extremely rough idling. It felt like it was going to die, and then rev to 700ish rpm.

I just pressure tested my engine and found that all of the cylinders on the rear bank (closest to firewall) are getting 0 compression. The front bank seems normal at around 135.

I thought I might be having a problem when I hooked up my vacuum gauge to the manifold when the car was idling really rough and noticed that the needle was jumping from 5-10mmHg vacuum. It looked like the jumping was directly related to engine speed.

My return line (the metal part aft of the fuel sending unit) is rusted and broken and therefore the fuel is not returning to the tank. Is it safe to just clamp up the rubber portion of the line so that the fuel doesn't leave the engine. The reason I want to clamp it up is because it looks like it will be impossible to fix without taking the fuel tank off and/or getting a new fuel tank and I don't want the line just pumping fumes near my trunk/exhaust or entering the car so I'm breathing it in while driving.

I just bought a 1991 Stealth TT with a fully rebuilt engine and tranny within the last 10k miles. The problem is when it gets above/around 3000 rpm it starts to shake/hesitate. I still have 40k miles left on my engine warranty but I'm wondering if anyone knows what the problem is. I heard sparks, and leaking boost are the most common problems.

1991 Stealth TT
-Engine Rebuilt in last 10k miles
-Tranny Rebuilt in last 10k miles
-Shakes/Hesitates above 3000rpm

Thanks for any help/input!

I know a bunch of you are running 13t's with like ~20psi boost but at the moment my car is running the 13t's at around 8psi with stock 360cc injectors. Why does it feel like it is slower than stock?? Am I that far out of the compressor efficiency range of the 13t?

Car has intake, FMIC, rebuilt bottom end, downpipe leading to stock exhaust.

Datalogged it, and the rear 02 sensor stays at 0.03v then goes to 0.05v for like 10 seconds then just stays at 0.03v, meanwhile the front 02 is functioning properly with fluctuating voltage

Timing hovers around 20-25 degrees under WOT and ~30 degrees under normal driving

Is the O2 the cause of the sluggish-ness? What is timing supposed to be at?

Thank you,

Ben

I am a single girl that has owned a 3000gt VR4 for the past 6 years. However out of those six years the past two years my car has been sitting. I thought I had locked up my engine because the timing belt was melted on the top. So I finally found an engine to put into it but it took two years to find a decent one. Well I finally had someone look at it and it wasn' t locked up. So I had it moved to my apartment and I have switched the timing belt out on it in my parking lot. Replaced the water pump, idler pulley, tensioner pulley and crankshaft pulley sensor(it was melted). And put it back together. I tried cranking it over and it started but then it died. Now it will not start, it just cranks and cranks but does not fire. Is there anything else that I need to check. I checked the fuses and the battery connection and that seems to be ok. I want to check the crankshaft and camshaft sensor but I thought the car had to be running to do that.
Please help me out. It is getting colder over here in the midwest and I don't have very many more days to get it fixed in my apartment parking lot! ]]> Engine - Turbo KrakrJack http://www.3si.org/forum/f35/may-simple-complex-enging-cranking-but-not-firing-478927/ http://www.3si.org/forum/f35/4-bolt-my-91tt-heads-fit-my-car-478898/ Wed, 11 Nov 2009 08:08:41 GMT Alright here is my confusing story. I am asking this just to be certain - what little info i got from searching helped somewhat..
the build is a
91 TT
with a 4 bolt short block. . prepping to go in.

I already know there will likely need to be some modding done for the CAS to jive with the 1991 ECU
Stealth 316 - CAS Conversion

(any other forseeable problems? ..)

my question is will my 1991 heads work on this (unknown year) 4 bolt and the rest of my setup. In the event i core them out which heads should i try to end up with (how many 'generations' of heads are there, anyway?). I am leaning toward some built heads but would like the option to stick with rebuilt stockers if thats an option. ]]> Engine - Turbo spinnin4 http://www.3si.org/forum/f35/4-bolt-my-91tt-heads-fit-my-car-478898/ http://www.3si.org/forum/f35/problem-car-doesnt-accelerate-shud-even-full-boost-boost-leak-478896/ Wed, 11 Nov 2009 07:29:35 GMT Hi guys.I'am from New Zealand and i just recently bought a 91 TT GTO :mitsu:.Everything in the car was stock and well kept.Only problem it had was that the rear turbos seal was gone so it blew bit of smoke and needed few adjustments hear and there.Having just finished automotive engineering and doing mechatronics currently,this car was a great practise for me to work on.Basically i was able to fix any problems that came along in this car till now.....

Ok this is my problem.Just few days ago i was tightening the loose fanbelt for the p/steering pump.Which obviously required me to remove the rear turbos pipes to make space to work.After i was done i took it for a run..well this is when the problem began..at very low rpm (around 3k) the turbo boosts like crazy and the car accelerates at the speed of a snail.The center console boost gauge reads more than zero whereas normally it wud be less at low speed and rpm..And when i floor the pedal,the turbo spools like a freaking jet engine and runs at full boost while the car will struggle to accelerate and will only be able to make 30km/h..It also blew smoke more than usual..which was more blackish than blue (running rich?)...and i think the exhaust gas doesnt completly escape the engine coz wen i open the oil filler cap,trapped gas escapes from there

What cud be the problem..is it boost leak or is the rear turbo(the one with the bad seal) is gone or something else...thanx ]]> Engine - Turbo rallyx8 http://www.3si.org/forum/f35/problem-car-doesnt-accelerate-shud-even-full-boost-boost-leak-478896/ http://www.3si.org/forum/f35/evo-scan-software-vr4-478876/ Wed, 11 Nov 2009 01:33:48 GMT Has anyone used the evoscan software an tactrix cable on a vr4??
