Hey guys I purchased an M20b25 from a race team years back and I having some issues. The engine was built with all new parts before the season, crashed on the 2nd race and didn’t run the car again. They had a mls head gasket that started leaking out of the front passenger side of the block after the accident. I ended up re decking the head, cleaning the block and installing an oem bmw head gasket and arp head bolts. That gasket started leaking again within a few weeks. Maybe 200 miles.
This isnt coming from the cam or anywhere, but else, it’s literally dumping out of the corner of the head gasket. I checked the torque specs on the corner bolt and it’s solid. being that this is an oil return line it’s hard to understand how it dumps so much oil.
In checking things out I did realize that my exhaust manifold was a little loose. I took it off and brought it to a machine shop who said it’s was extremely warped because of an exhaust leak on the farthest cylinder from the driver.
I’m wondering if an exhaust leak could warp the head enough to create a serious head gasket leak.
