Update from my previous post, coolant seals went out

so after i replaced the lower intake manifold gasket and the orings the real problem finally showed itself. it looks like the coolant seals did blow as coolant comes out of three spark plug holes. it didnt show itself before because the coolant was coming out of the intake manifold gasket.

Also there is coolant coming out underneath the car too, but i cant see from where. Car still wont start obviously because of the coolant seals, i do have strong compression as the engine was rebuilt around 3k miles ago. What should I do in this case? replace the coolant seals only or do all the seals?

i figured it would be something along these lines when hinted that coolant was getting into the engine, i have never seen a faulty LIM o-ring cause coolant to go into the engine.

if it only has 3k miles then you should be able to just replace the coolant seals. but i suspect you will find a cracked iron coolant seal wall when you tear it apart. the cracks can be repaired and i do it for $85 per crack(if that winds up being the case and you can't find replacement iron/s).

Well I planning on somewhere between 350-400 rwhp when done. Nothing to crazy, I'm going to be auto crossing and doing road courses. I'm probably going to get a mild port done while I have it apart.

What sticks about having to rebuild is thai my compression is great. I wish I could fix the seals without having to treat apart everything

i would make your goal to be 350whp and use the traditional Goopy/RA/ALS for your apex seals since it isn't going to be strictly a street driven car.

going beyond that you should consider reinforcing the block, like aftermarket stud kits.

and don't let coolant sit inside the block, the longest it should be left is a few days to possibly a week before it will begin rusting up components and damaging expensive parts.
