IF you have the rubber plug at the back on the side and IF you are using a B34 or earlier oil canister you will need a 10 mm FINE thread plug in the block or you will get no oil pressure.
I buy the bolt at the hardware store, cut the head off and cut a groove at the end for a screwdriver. Red lock tight also.
I am using the same 3 bolt holes for the the left side engine mount and the same 2 on the right as they do when putting in a b35. The engine mount configuration seems to suggest from what I've read that it's a b35?
The block number search online using realoem... tells me it's an 87 535I with a manual transmission.
Car has been running well but i recently found some oil in my coolant! Not a huge amount.. but after I flushed everything it came back within the week.
It doesnt overheat and there doesnt appear to be a visible amount of combustion gas bubbling into the reservoir. The oil is clean... no indications of water on the stick or on the oil cap.
Any recommendations on things I should look for before I pull the headgasket???
As this is a 34 lower half and a 35 head anything special I should know before I purchase the gasket?
Oil in coolant often is cracked block at headbolt bore. Inspect each head bolt bore hole at surface of block for fine cracks to water jacket. Cause of this is cleaning bore holes ot oil when installing head.
Ill pull the head and look to see if I can see any splits. Im guessing this kind of crack propogates from the block deck down, so repairing isnt really an option?
In your experience.... whats the probability of this being a head gasket? Is it to the point where its not even worth opening up the head?
Two answers for you..
Do a compression test and if all is well then just keep driving
Funny thing about oil in the coolant....
I drove my 745i turbo like that for five years.
Twice a year I would pour dishwashing soap into the expansion tank, go for a spin and then flush the system. Important how you flush it ask me details.
I wouldn't pull the head. You can buy a lot of Palmolive for the price of a head gasket.
I went forward and pulled the head and the block doesnt have any cracks. I replaced the head gasket and have been driving it for the past week. no more oil.
I also bought one of those aluminum radiators that you see on ebay all the time. I have to say that I was surprised with the fit and welds.
I had temperature creep when running up long grades and with the A/C on. This radiator seems to have cured the problem! Unlike the brass radiator, you can feel the heat coming off the radiator with the fan on and after driving it today it hasnt gone above middle!
