Hey not sure if this is the right place but...

I have found a 535i manual to use as my doner car for a possible engine conversion but it has an oil leak. its at the front and looks like its coming from the sum/block join. as the engine is coming out i will change it but could this be something else to worry about.

I cant see exactly where its coming from.

Thanks in advance

Could be the front crank seal.

Ahh thank you. I did not think of that will check tomorrow. is it a easy fix?

is it a easy fix?

Remove the crankshaft pulley and vibration damper, Prise the old seal out of the cover, Clean it up, coat the new seal in engine oil or grease, then using a socket or bit of pipe with an outside diameter of the seal drive the new seal into place and then replace the damper and pulley.

it might be worth pulling the sump for a cleanout and checkover anyway so the sump gasket and both crank seals could be done then. afaik there isn't anything else further up on a M30 that can leak oil other than the head gasket. this would be obvious though.

thanks alot guys

its the front cover bolts, mine leakes from their, stick some gasket sealent on all the bolts includind the front pully sensot bolts

Beware if you are removing the crank pulley nut - it is VERY tight!
An air gun is useful here. I don't have one and ended up cutting mine off!

thanks guys for your help. i will be driving this car till after xmas when i can get a good shell.
