Odd issue


Recommended Posts

This is an odd one. Let me start by saying I’ve used this forum for troubleshooting a lot of issues with 32 Gtr.

I actually bought the vehicle at a salvage yard and for the most part the rebuild has been going smooth. Intercooler, turbocharger inlet pipe, radiator and ac condenser have all been replaced. I did the 3 belts along with the tensioner and notice a squeal coming from p/s belt. Turns out the high pressure line was leaking at the O-ring, again this forum provided the answer. Replaced the O-ring and bought a new reservoir cap b/c the previous one had wires that snapped. 

Turned the motor on to see everything in action and the belt still squealed and I the pump had a slow but consistent leak from behind the pulley where it meets the power steering pump. 

Now it’s been about a week since I last worked on the car and noticed power steering fluid coming from the bottom of the radiator? I posted a pic for reference and I’m racking my brain trying to figure this one out. Maybe when the fluid was spraying inside the engine bay some of it got caught in the radiator? I also just put the car on jack stands because I have 3 droplets of coolant forming beneath the oil pan ?‍♂️. According to my forum research it can be the heater core or a few nuts located under the plenum. I appreciate any insight on this one or even reassurance that i’m not totally Burnt. Thank you for the read and help.

Degrease everything. Make sure it is clean everywhere that has oil on it now. Run it for a bit, see where it gets wet.

Squealing belts/pulleys can be fixed by sandpapering the sheave faces. Don't do it while it's running! But the squealing may be because the pump has a problem. See how hard it is to turn, whether there's any wrong slop in it, etc.

?? i will try the degreasing next. I thought it was a bad pump at first listen but when I sprayed the a/c belt With a tad bit if water the noise went away temporarily. Thanks for the suggestion

Also I had added some ATF to my power steering and turned lock to lock. The steering isnt jittery any more and the squeal stopped when at idle but if I were to rev the motor it would let a scream out momentarily

So I degreased the potential problem areas and found some interesting stuff. I knew my power steering pump seemed expired but Unfortunately I came across this sight. Any ideas? 
 

You can see the coolant gathering under the oil pan. You can also see a droplet on one Of the Hicas lines in the front. Could it be a bad gasket? Bad water pump? Thanks everyone for your help

Trace the wet up to where it comes from.

It is not unusual for the water pump to start to leak at the shaft seal, sometimes even at the gasket. These things need to be replaced every so often.

The PS pump could be leaking from it's shaft seal, from a hose connection or a body seal.

You know what fluids are leaking, you know what they are supposed to be kept inside. You just need to find out where they are getting out.

Thanks GTS, I appreciate all your input. Im going to rip apart the front end and just do it right this time around.

    • Lighting in the shed looks real good! Not lying, have shed envy lol. Maybe one day I can fk off from Metro Sydney.
    • I would be cautious with those 2000/2200 CNG injectors, swap them out for a set of 1550 aka 1650 Bosch stainless ones before you take out a motor.
    • I tested them all a couple times, haven't tested it warm or wet though. The only seemingly really weird thing was the cylinders plug closest to the dash was pitch black nearly.  Doesn't smoke out of the exhaust or anything.    Also sorry everyone for the very late response. Got busy with work and all and didn't get around to fooling with the car for awhile.  But an update! I figured out the cause of the lean condition, my intercooler had at some point exploded or something. It's clearly separated in a spot with black oily buildup around the leak, and multiple leaks in various vacuum lines. I've replaced it and the vacuum lines, and gotten new clamps and there are 0 leaks now after doing a couple smoke tests.   The car now runs significantly better and the exhaust doesn't overheat anymore. I still have the main problem though where the engine feels like I'm lugging it around sub 3500rpm in any gear besides 1st, 2nd It's less noticeable but 3rd anything under 3.5k and I need to downshift or the engine is clearly struggling when trying to accelerate at all, 4th is the exact same, sub 3.5k engine won't accelerate and its hard to bring it back up to speed, 5th gear doesn't feel like the car is going to straight up fall apart now but it still can't pull 5th. It slowly loses speed and rpm and ANY gas I give I can feel the shakes from the engine and it slowly dying. If I ever so lightly give it gas it will slowly and nicely decel till around 2k rpm instead of lugging. But it cannot accelerate at all or maintain speed.   If I go from first gear at 5 or 6krpm and then shift to second it also feels like it's struggling to make power till above 3krpm if trying to accelerate but I can cruise around parking lots at around 1-2krpm just fine in 2nd. It's just when accelerating hard it and changing gear you really notice it die down.  But even if you shift at way lower rpms it does the same thing till somewhere above 3k.  As far as I'm aware it's got r32 gtr transmission gear ratios with gts4 diffs. The tire size is 205/55r16 91h Above 3500rpm the car pulls and runs and drives quite normally and the power from engine sounds and feels very smooth.  It's perfectly driveable at above 3.5krpm but I drive on the highway alot for work and it gets really bad gas mileage in 4th at 4.4krpm. Not that I'm looking for great gas mileage with such a car, just I'm sure being at around 3krpm would be significantly better for it.    Have appreciated all your guys help. I do understand the engine may just be f**ked from running with a boost leak though.    One final thing I'd like to add is I'm only shifting so high in the rpm range is because if I don't I will feel the engine lugging bad with 0 power in lower rpms, pretty much anytime off boost trying to accelerate it feels really bad.  Also when I say 3500 rpm I don't mean exactly. Just around there. 
    • So what did you end up doing ?  and is it still alive today ?    
    • I run 2 x 525 pumps on factory 8mm fuel lines     ... zero issues, staged of course    Your setup should work fine, all you need to do is find the restriction. A good aftermarket fuel regulator is always a good idea too. If it's not your regulator i'd be suspicious of your fuel tank breather and your tank pressurising. Next would be something with the fuel hat. Then blow out the fuel lines.
