yes i do know what it can be but it would be best if you checked for codes first.

 

Well not to sound like a newb but how do you check for codes i saw a thread about it but i cant find it in the search button... and what do you think it can be to be causing it to do that ??

 

there are quite a few things that will cause that problem but i'd only be guessing. download the fsm all the info is in there.

 

Well we decided to take a look at the bottom end and do a compression test and with the compression test it was in the 175 across the board... but we came to find out that the motor is not gettin any lubrication because of the oil pick up tube or sumthin like that but yeah now they are gonna check the crank to see if it scorred or damaged.. all i wanted was my car to run and now im having to do a complete rebuild on this B*tch... I cant complain atleast i kno it will be reliable lol

 

how is is that you know it's not getting lubed?

 

Well the mechanic i took my car to knows this guy that races 240's and he told me that you got good compression but your not getting any oil lubrication... he said something about the oil pickup tube..

 

Well the got the rod bearings changed and also the oil pickup tube with a new oil pump but we still got this wierd oil copression problem the guy tested it with a guage and everything so idk ne thoughts on what it could be

 

define weird.

 

Ok well he put his racing oil pump in my car and he oil pump runs at 100 psi when he put it on mine it was only 20 psi then he tried a oem one and still the same thing then he took my oil pan down and he had found a piece of my block in it

 

was the engine running or was this reading from just cranking it. the oil pressure is mainly determined by the engines rpms. that's assuming you have a proper seal. so depending on how it was tested 20psi with three different pumps would lead me to believe that that's not a problem.

the piece found in the pan, are you sure it's from the block and not a part of a the timing chain guide?

 

1)He is reading it with the engine running and 20psi is the car just idling at around 700 rpm but cruising around 3500rpm 20psi is not going to do anything... He tested it with the guage and revving up im guessing..

2) im positive its not a part of the timing chain guide because we just replaced that like last week..

What we did:
complete rebuilt head
all new seals
Water pump
Timing chain
New rod bairings
new wire harness
Removed egr valve
and a couple other things when i remember i will list them

 

i'm not sure i understand could you rephrase this. with the engine idling at 3k rpms you should have 60-70psi though.

 

Yea but it only stays at 20 psi never goes above that with any of the pumps

 

sounds like it's time for a complete tear down and rebuild. if you do go through with this make sure every thing is torqued to spec and all clearance measurements are within tolerance.

 

Yea man thats not what i wanted to hear... I guess its just time to cut my loss wit the KA and go SR20 or RB20...
