HEAD GASKET

1999 Dodge Neon

Engine Mechanical problem
1999 Dodge Neon 4 cyl Front Wheel Drive Automatic 96000 miles

original problem, leaking oil from the back right corner below the head gasket. Went in replaced the head gasket, car wouldn't start but saw antifreeze in oil. Crap, tore down again checked head and had resurfaced, replaced head gasket/bolts. Car runs but still has antifreeze getting in the oil. Have torn down a third time and had the head pressure checked and flatness checked, flatness checked the block, Mechanic at the shop said he didn't see anysigns of failure in the head gasket? What could it be?

No, the block has not been checked but it originally didn't show signs. I don't see how the block could of cracked since it hasn't been run except at idle. There's never been any time it's been left with water only in it for a freeze situation. Is there anyway to test without removing it?

Bolts 7, 8, 9, 10 Are the SHORT bolts!
Get all new bolts, they may have lost sealing and gripping ability!

All the above was followed. Anything else that it could be?

You compare head gaskets to be sure you have the correct one?

Yes, the gasket was correct

Merlin may have hit it with the long/short bolt idea. No sealing power if the bolt is bottomed out

No, the bolts were new and the short bolts were in the corners, There's at least 3 inches difference, you wouldn't be able to make that mistake.

If im not mistaken pressure checking the head might not show a crack, magnafluxing will though, also it could be an intake gasket leak

You might want to have a ppek at the threads in the block. If damaged you may need to helicoil them.
