RE: Oil pressure questions

[Gfbourcier@aol.com]

Bill,
BTDT very recently.  The key is that you have to think "where" in the system 
the sender is reading pressure.  On the 4KS (4 cyl, I believe), you removed 
the sender from the oil filter mount housing.  On your 4KCSQ (5 cyl.) you 
removed the old oil temp sender from the block.  After my same problem, I 
went back to a scrapyard and pulled the sender from a CGT (5 cyl.) that was 
mounted on the block, and swapped them out (darn, that metal hose is sure in 
a bad place!)  Although I couldn't discern part numbers from the senders, I 
believe them to be two different units.  The only time I peg 5 bar now is 
when the oil is cold.  Normal operation at highway or under load is about 4.5 
bar.  Something else I discovered while doing this was a bad crankcase vent 
hose (totally melted and leaking like a sieve.)  It was a short section so I 
replaced it with some leftover from changing hoses a while back and have seen 
improvement in cold start situations.

Hope this helps you out,
