Hey all,

I've got a J35A6 v6 that popped the timing belt last week. Tore the heads off and inspected the valves and pistons. I'm rebuilding the heads with new valves and the pistons looks fine for the most part. I've got two where the valve slap was hard enough to leave the smallest of indents on the edge of the factory milled cutout for the valve. Looks small enough I can debur the edge and be good to go. I haven't pulled the bottom end to check the skirts or anything lower as it doesn't seem like everything hit too hard.

You guys know honda engines, so I wanted your opinion. I can get pics later if needed.

Also, any tips on other issues to clean up while im in the block for these things. It's in an 06 honda odyssey. Vans got 215k. Hoping to get two more years out of it I can (20k miles tops).

 

I would just deburr the marks and that should be good enough. For each piston that needs deburring, raise the piston to TDC and tape off around the mark so you limit grit and metal dust from getting in the rings and on the cylinder walls. If it was just a timing belt break, I wouldn't worry about tearing the bottom end down. If you've got oil leaks, now may be the time to address them with fresh seals/gaskets if you have easy access. You'll obviously install a fresh head gasket and timing belt, and I would go ahead and do a water pump too. If the timing belt tensioner feels smooth, put it back in. If it doesn't feel smooth, replace it. With the heads off you may have good access to some otherwise difficult-to-reach coolant lines that may be brittle and old - replace as needed.

 

Awesome, thanks for the tips man
