Oil pressure warning.

[PhilipJCaputo]

Holy ****! Why doesn't every one use an oil pressure gauge? Low cost and simple to rig. Even GM light duty trucks come stock with OP gauges. Even our '93 Chev S10 4.3 has one.

can you check the oil pressure from the OBC?


wheres the thread with the instructions to install the gauge?

[PhilipJCaputo]

You should be fine. You see how bad mine was, and I only got the oil pressure warning light at idle, so as soon as you get some speed going it'll be pumping ok. Its a simple job, but some of the bolts for the pump are somewhat difficult to get to. Are you also going to replace the gasket?

yep, put a new gasket on.... also, when the bentley calls for 89 INCH lbs of torque.. you'd better believe it.

I snapped one of the oil pan bolts right off... had to drill it out.... looks like tomorrow I'll hit a hardware/autoparts store and get a replacement.

All of the oil pan bolts were the same size.. except one was about half the length... anyone notice something similar?



it was pretty clear that the pan had been taken off before, because there wasn't a guard around the pump sprocket/chain, and one of the bolts didn't match the others (didn't have the same 8.8 stamped on the back)

89 inch pounds??? WTF

[BillionPa]

well, just dropped the pan 5 mins ago...

only 1 bolt at the bottom!!!

im betting all the sludge down there kept them from coming loose!

looks like a rugby field in the rain.

luckily i have about 6 bottles of Auto-RX just for this occasion!

I also got all new o-rings and a new oil chain, and a new pressure control piston assembley, time to rebuild the pump.

thats what the bentley says.... I was trying to do the math in my head and dial it in on my torque wrench.... but I think it was too far down on the low end of my torque wrench's scale, so I couldn't feel it when it clicked.

obviously a nikasil failure... brake cleaner spray in the bolt hole with compressed air should make a good fit for loctite.

What's general concensus on using the Loctite? Definitely don't want to risk letting this float around.

spray the bolt holes and threads nuts etc with brake cleaner or whatever to remove all traces of oil. you should also wait 24 hours before you heat it up to temp. dont use too much and none should drip oit.

I was having similar issues about a year ago... I dropped my pan and all of my oil pump bolts were tight. I ended up taking it to Truett at www.stgbmwservice.com for him to look at it. He ended up replacing the pump, but noticed bearing material in the oil. Looks like it needs a rebuild! I haven't messed w/ it since Oct. 05, but am finally going to tackle it!!! I haven't driven it in over a year and miss it!!

I talked to Allen Patterson the lead tech at Korman (www.kormanfastbmw.com) about rebuilding my engine. He recommended I buy a new shortblock from BMW, which would cost about the same as machining the old w/ new pistons etc.

Take my advice... Do not drive your Bimmer w/ a low oil pressure warning!!! It'll probably cost me at least $5K to get mine fixed! That's more than my freakin car's worth...

Arent you worried about the AutoRX loosening the sludge and clogging the oil passages?

[BillionPa]

it doesnt loosen the sludge, it liquifies it slowly over about 2000 miles then lets the oil filter take care of it.
