rioyellow Posted August 28, 2011 Report Share Posted August 28, 2011 I have a G54B i took apart to but a T3T4 turbo port and polish head and a balance shaft elimination kit. I put oil in the oil pump then i put the motor back together i start the car the oil presure is very low,and before i took it apart the oil presure was good. What can be the problem ?

Guest Posted August 28, 2011 Report Share Posted August 28, 2011 (edited) When you did the balance shaft elimination kit, did you put the bolt in the oil pump, the one that goes in place of the balance shaft? Better yet, What balance shaft elimination kit did you use? Edited August 28, 2011 by louswheel01 Link to comment Share on other sites More sharing options...
rioyellow Posted August 28, 2011 Author Report Share Posted August 28, 2011 Yes I did and the kit I toke it off my other runing motor Link to comment Share on other sites More sharing options...
Hoosierquest Posted August 28, 2011 Report Share Posted August 28, 2011 (edited) When you remove the shafts you have to put in a sleeve in place of the upper shaft bearing to block the oil feed to the shaft Edited August 28, 2011 by Hoosierquest Link to comment Share on other sites More sharing options...

intense98rt Posted August 28, 2011 Report Share Posted August 28, 2011 Is your pickup tube sealed properly? Link to comment Share on other sites More sharing options...
rioyellow Posted August 28, 2011 Author Report Share Posted August 28, 2011 yes it is and i put a new o ring and it still haves low oil presure what eles can b worng with it Link to comment Share on other sites More sharing options...
Indiana Posted August 28, 2011 Report Share Posted August 28, 2011 The sending unit might just be full of crap. That little hole, all the dirt and small piece of anything can get in there and it doesn't come out and when its full and packed in there the oil pressure doesn't move all this junk and cause a change to be seen at the gauge. A loose dirty wire on the sending unit will also do this. If you plug the wire on the gauge doesn't instantly jump up its V E R Y S L O W to move and what is a bad connection shows up as pressure that seem to move up and down and look strange. You can try and clean it out but its not easy, the hole is very small. You might try spraying some cleaner in there and see how much of it you can get to come out.

Indiana Posted August 28, 2011 Report Share Posted August 28, 2011 Its the hole in the end of the sending unit. Its screwed into the oil filter adapter. Link to comment Share on other sites More sharing options...
Tim_C. Posted August 29, 2011 Report Share Posted August 29, 2011 That oring at the pick up tube can look sealed when it isn't. The pipe is easily bent without knowing it, and it will not fully depress the oring when installed. The elim can't be done correctly without pulling the oil pan. Hopefully you did that and made double sure the oring is being depressed as the pipe mount bolts are being tightened down. Link to comment Share on other sites More sharing options...
rioyellow Posted August 29, 2011 Author Report Share Posted August 29, 2011 it my secend time changeing the oring everyting looks good cant find the problem Link to comment Share on other sites More sharing options...
Shelby Posted August 29, 2011 Report Share Posted August 29, 2011 (edited) you have not once said what the actual oil pressure is on a mechanical gauge ,,playing arround can result in a no engine . ANY oil pressure problem the FIRST thing to do is install a mechanical pressure gauge to SEE what the actual pressure is,this tells you if you actualy do have low oil pressure or it;s a simple sender problem Edited August 29, 2011 by Shelby Link to comment Share on other sites More sharing options...
rioyellow Posted August 30, 2011 Author Report Share Posted August 30, 2011 I just put in a gauge today wen its cold and I start it up it gos up to 50 psi and wen its warm at idol it's 19 psi Link to comment Share on other sites More sharing options...

rioyellow Posted August 31, 2011 Author Report Share Posted August 31, 2011 Ok now if my rod bearings are bad will that b a reason y I don't get good oil pressure Link to comment Share on other sites More sharing options...
Indiana Posted August 31, 2011 Report Share Posted August 31, 2011 Maybe, maybe not. A rod bearing can knock if there's just a very slight clearance issue and you wouldn't lose any pressure. Your oil pump produces WAY too much volume when the rpms are up. At 3000 its puking oil out a relief valve when the pressure hits about 80. http://www.b2600turbo.com/images/lubrispec00.jpg Link to comment Share on other sites More sharing options...
Shelby Posted August 31, 2011 Report Share Posted August 31, 2011 gas in the oil will do a number on pressure readings,, check with a fresh oil change , normaly it takes a major oil leak to lower over all pressure a lot, like worn out bal shaft brgs Link to comment Share on other sites More sharing options...

Shelby Posted August 31, 2011 Report Share Posted August 31, 2011 rare but if an oil squirter wasn't tourqe'd properly , it can come out and cause a low oil pressureas can a sticky pressure relief valve Link to comment Share on other sites More sharing options...
rioyellow Posted September 23, 2011 Author Report Share Posted September 23, 2011 Ok I'm now on my second motor and turbo but still I have low oil pressure. I drove the car and its so slow and turbo dose not boost and oil pressure is low. its ok wen I first start the car oil pressure gos up to 80psi but wen its hot its gos down to 16psi. I'm on my second block and still low oil psi and I did change the oil pump can the rod barring couse low oil psi. What eles can it b this car is driving me nuts Link to comment Share on other sites More sharing options...

Indiana Posted September 23, 2011 Report Share Posted September 23, 2011 You took the timing cover off but didn't take the pan off and look at the bearings? When the engine is heated up and you are at idle, 20psi is about all you'll get and more than you need. Not making boost isn't because of oil pressure in your case. There's some other reason it won't build boost like clogged exhaust. Link to comment Share on other sites More sharing options...
