Hey guys,
I think my engine has retired. I tried cranking her up after sitting for about 8 months and no luck. I did a compression test on one of the cylinders and it's at 30. I have done overhauls before but just do not have the time to do so now.
I am looking for an M60b30 for a 1994 530i 5spd. would it be worth it to replace the motor or just get the heads and piston done? it is a nikasil block with 160,000 miles on it.
Any feedback will help. Thanks,
while you are doing the swap, why not put the 4.0 and 6sp tranny in? There are a couple of guys at bimmerforums looking to sell the 4.0 and/or parts car.
no deals on the piston swap, the Nikasil is a coating and if its worn at all it will be the same as before. Have you tried squirting a little tranny fluid into the dead hole to bring the compression back? Might not be a bad engine.

i've had 318s take almost a hour of ****ing with to get going and then after the rings reseat it's good to go, after it starts run it at 1500-2000 rpm for about 2 minutes to clear the air out of the lifters and seat the rings
Hey thanks a lot guys. My mechanic just told me to do the same thing with the ATF. I have never heard of it before but will be more than happy to try it. Wish me luck. As far as the 540 swap, will I only need to swap the engine and tranny, or will the diff need to be swapped too?
