Head gasket repair now wont start


Recommended Posts

I have a 99 Legacy Gt Sedan and my head gasket went at 149k. I pulled the motor replaced the gaskets and put the engine back in i have the timing marks lined up as best i can but the motor wont start just misfire and has hard turn over points. Might that just be timing or something else?

Welcome to the forum. Hopefully we can help.

 

The conditions you've described are indeed likely due to mistiming, possibly by not using the correct alignment marks. The engine in your car is of 'interference' design, and the ''hard turn over points'' could be instances of valves and pistons contacting each other. Unfortunately, that contact is often destructive, resulting in bent valves.

 

In case you've gotten lucky, you might try to redo the timing. The following are some articles that should help:

I was having a similar problem. Turned out to be the timing was 1 tooth off. Threw it out a lot more than I thought it would.
