No compression 5 thru 8
1985 380SE 126 116.963 3.8L V8.
Started with a no start issue check all the relays ect. did a compression test today and 1 thru 4 were all at 121 or 122. 5 thru 8 have 0 lbs. The needle does not even flicker. I havnt taken of the valve cover yet kindof afraid of what it may look like. Does this sound like a head gasket or maybe the cam on drivers side? I have no idea what to expect. any help is much appreciated Thanks again for your time and for sharing your knowledge. This site ROCKS!!! Don |

Timing chain jumped. Now may have bent valves.
Sorry to be the one to say this.

Valves open are the only way to get zeros. Sorry. Tom W

Expect to lay out a good bit of $$ to fix it properly...likely more then the car is worth unless it's in pristine condition otherwise :-/
Were I in your shoes I'd start looking for a Euro 500 drive line to drop in. Jonathan

Valve damage is going to cause a certain amount of comotion and calamity from metal hitting metal. If you didn't have that you may not have a ruined engine. A jumped timing chain doesn't necessarily ruin an engine.
