RE: Re: 3.5 bars??????

[Jonas Karlsson <jkarlsso@metabolex.com>]

The current back-and-forth of idle oil pressure seems to be consistent 
with the little -FYI- bit in the Techtonics catalog. In the section with 
the oil pumps, baffles, etc. there is a little blurb about how solid 
liftered cars run a normal oil pressure of 30 - 90 psi. Didn't say about 
idle, (prob ~30). Then it goes on to say that the cars with hydraulic 
lifters ran a much lower oil pressure. 10 - 15 psi or lower at idle.  So 
I wouldn't worry. As long as you have enough oil, the right oil pump for 
your engine, and there's no major leaks, you should be fine. 

BTW. I put in a hydraulic head with 9.5:1 CR, along with the oil pump, 
and my oil pressure at idle & 100C temp is between 6-10 PSI. I do have a 
leak from what looks to be in the region of the oil cooler, and I'm 
questioning weather the oil pump was the right one after all. So I might 
be a little too low. Plus the idiot light comes on sometimes on the way 
home from work if there is a sudden traffic jam, and the RPM's drop 
suddenly to idle. 

Hope this clears up the confusion

PS. If anyone has an oil pump lying around from an >86 VW with hydraulic 
lifters (bonus if from a 2.0l) I am looking to buy one. TIA
