stg4100 Posted March 21, 2009 Share Posted March 21, 2009 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? Link to comment Share on other sites More sharing options...
davebugs Posted March 21, 2009 Share Posted March 21, 2009 Did you follow a good precedure (like the Endwrench procedure)? Make sure you used the correct mark on the crank pulley(one in the back). Everything plugged in (I'm thinking crank and cam sensors). Link to comment Share on other sites More sharing options...
OB99W Posted March 21, 2009 Share Posted March 21, 2009 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: 2.5 Liter DOHC timing belt: http://endwrench.com/images/pdfs/TBeltEWWin05.pdf http://endwrench.com/images/pdfs/2.5Timing.pdf Motor Magazine series; starts with 2.2L, then moves on to 2.5L: http://www.motor.com/magazine/pdfs/072001_08.pdf http://www.motor.com/magazine/pdfs/082001_08.pdf http://www.motor.com/magazine/pdfs/092001_08.pdf http://www.motor.com/magazine/pdfs/102001_08.pdf http://www.motor.com/magazine/pdfs/112001_08.pdf (last one includes new-style tensioner info) Link to comment Share on other sites More sharing options...

Might that just be timing or something else? 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.
