yeah, a little compassion..English is not everyones first language, but when someone reaches out with a car problem, they dont need a lesson on the three Rs...when your oil and water mix it sucks in any language:eek:

Yeah, easy on the criticism. A bit of compassion and tolerance would be greatly appreciated.

BTW, his banner is the flag of the Republic of Bosnia and Herzegovina. My Great-Grandfather came from that region to pursue the American dream 'round about 1889. So I don't mind the occasional misspelling...

But enough of this thread-jacking... I want to see some pics of a repaired cylinder head!

Thanks for defending him guys, ill type this up for him so your head doesn't hurt. No need to be arrogant, this is my dads username and we came to this country 14 years ago. He never went to school here and yet his English is still better than some of the people on this forum.

Anyway, on to the problems. The engine has consistent compression all the way across and everything seems okay. He took the head to the machine shop and had it resurfaced to make sure that it was 100% straight even though the machinist told him that he didn't have to have it done. He also replaced the valve seals just in case. The car idles and runs fine. After about 30 minutes the mixed coolant starts to rise to the bleeder valve on the top of the radiator. The car never overheats and idles smooth as can be. It pulls a lot less oil this time from the block than it did after doing it the first time. After we did it the first time within minutes the dipstick wasn't showing any oil. Also, the oil service light is on

Things that have been done/replaced:
Resurfaced head
Valve Seals
ALL gaskets Including head-gasket
New Thermostat
All vacuum and fuel lines
Fuel Filter
Water Pump
Coolant temperature sensor

Anyone have any ideas/suggestions?

This is the car after 30 minutes of idle

I'm still thinking that there's a leak somewhere on the head in a cooling jacket but I'm no expert. Someone that's torn a few of these down should know for sure.

BTW, did you check the upper oil pan bolts? They have a habit of loosening up & letting the lower pan gasket break the seal. Oil pressure fails.

He has it torn down to the bare block with basically only the pistons and crankshaft. Everything seems fine and everything we took apart looked fine during tear down. Can someone list out all the possible places where the coolant and oil can mix and we will just get all new gaskets and check those spots while putting it together. He also got the head pressure tested today at a local machine shop and its not leaking anywhere.

The head had a small crack in it and they said they fixed it. Have put 20-25 miles on it since and its driving fine. New seats are in as well. My dad made a mistake yesterday though when switching antennas.

He was switching out my power antenna and he accidentally put the power wire on ground and ground on power and it shorted something. The cluster and radio don't work. Fuses 8 and 21-30 didn't blow but aren't receiving any power. Any Idea on what shorted? We tried switching some relays but no luck.
