Date: Tue, 01 May 2001 13:41:06 From: "Ron Buchalski" <rbuchals@hotmail.com> Subject: Re: Oil Temps, was Re: JTD OTB Questions/Comments Bob, The coolant temperature would be much hotter than the oil temp, if not for the radiator (which transfers heat out of the system). The coolant flows through the water jackets around the cylinders (primarily), and on the other side of the water jacket is the combustion process, which is where all of the heat is generated. The heat transfer characteristics of the cylinder block (iron or aluminum) will determine how much heat is transferred across this metal boundary, and at what rate. Plus, the coolant is always flowing, taking heat away. Try disabling your water pump and see how long your engine lasts. On the other hand, the oil flows through oil passages in the block and head, and circulates through the oil pan. Oil is also sprayed at the bottoms of the pistons. Unless your car is equipped with an oil cooler, the only oil cooling that takes place is via airflow across the oil pan, and heat transfer through the oil pan walls. Since the oil doesn't get nearly as hot as the coolant does, this is adequate for most purposes. For racing and/or extreme service, an external oil cooler is normally used. So yes, under hard use, the oil temp can exceed the coolant temp, but the difference isn't great (tens of degrees), because the coolant is drawing away the majority of the heat generated (other than what's blown out the exhaust pipes). If your thermostat failed, or was set for an non-normal temperature (say, 240 degrees instead of 180), your oil temp would also rise a comparable amount (if you didn't have an external oil cooler). -rb >From: M Driver <m3tec@yahoo.com> >To: e36m3@bmw-m.net >CC: rbuchals@hotmail.com >Subject: Oil Temps, was Re: JTD OTB Questions/Comments >Date: Mon, 30 Apr 2001 20:53:32 -0700 (PDT) > >Ron, > >This is an interesting observation. >From my experience w/ other engines, oil temps are >usually 20 - 40 degrees higher than coolant temps. >I attributed this to the oil is transferring heat to >the coolant, therefore it has to be hotter. >I am sure it makes a difference at what point on the >engine you are measuring temps. >I also use this analogy: To see which fluid transfers >more heat, drain each fluid and see what fails.

The later tool runs > for about $155 or so. It was pretty easy to do. I'm sure it would be nice to have the BMW tools, but it's certainly not necessary. I used ordinary pullers when I did my front wheel bearings. Instead of the insert tool Chester mentions you can slip a socket in there for the puller's central screw to bear against. I now also have a generic wheel bearing removal tool which I bought at an auto parts store for about $25. I had to enlarge its mounting holes just fractionally for the BMW application. It attaches to the hub with lug bolts, and pulls the hub right off using a central screw. If anyone feels a wheel bearing job coming on, I have a write-up on the procedure. It's not hard.

I had a compression check and leakdown before I bought the car at 146k miles. All cylinders were between 174 and 176 psi, and 1-2% leakdown. At a recent autocross, according to a friend, the car blew black smoke during upshifts near redline. Does this mean the valve guides are worn? Or is there another way for the oil to get into the exhaust, for example, pcv valve, etc.? I assumed the engine was in fairly good shape because of the compression and leakdown readings. Thanks in advance!

Or is that not possible with today's engine management? Also, could it be some build-up of soot in the exhaust?

It was my understanding that: - Black smoke = Fuel - White Smoke = Coolant - Blue Smoke = Oil I know white smoke is burning coolant, because I have seen it coming out of the tailpipe of many friends' cars. My old VW had blue smoke on start -- oil deposits on top of the cylinder walls burning -- which a head job remedied. Black smoke? I've never seen it so can't verify the cause. If you think an imbalanced fuel condition is causing the black smoke, I'd make sure that the car has a fairly new O2 sensor. The're supposed to get replaced NO LATER than 100k, but I have heard a few stories lately of them never being touched. I know other folks who do them every 50k. As our cars age, the maintenance bits become more and more important. -peterg ------------------------------------------------------------------------------------------- This message was sent using HiSpeed Technologies Webmail. http://www.hispeed.com

Ok here's an idea for real real cheap hp. Get signed off at your next event and assuming your instructor is around 200lbs (from my experience this is being quite conservative :-) ) and you've just added 20 hp! Woo hoo! Cheers, Jim E.

#10. Time to replace a light bulb? - from david tow

I took my car back from "The Driving Machine" after Inspection II and noticed the clock's light bulb's out on the way home that night. I called the service advisor and he agreed to replace it free of labor except charging me for the light bulb. One condition though; I have to have my smog check done there for $55, which should be around $24 anywhere else. How much time does it require to replace a light bulb for the clock? Part cost?
