Imp558 Posted May 30, 2017 Report Posted May 30, 2017 Pull the plugs and inspect them. Look for evidence that there's water in the cylinder. Also, look for bubbles in the coolant. You may yet have a failed water pump or thermostat. Don't jump the gun. 1989 Pontiac Se and Galaxie500XL 2 Quote
dogginred90 Posted May 31, 2017 Report Posted May 31, 2017 2.8 heads love to get hairline cracks at the spark plug holes. I had a couple sets all the same cracks in the same places. Exhaust gases entered the cooling passage and had overflow bottle boiling. I would guess the heads before the gaskets, but I may be wrong. Ask my wife and I am always wrong lol. 1989 Pontiac Se 1 Quote
1989 Pontiac Se Posted June 4, 2017 Author Report Posted June 4, 2017 Okay so i had new ones put in like two days and i drained the watery oil out of the motor and coolant from the radiator. Where do i start as far as diagnosing goes. Sent from my LGMS210 using Tapatalk Quote

Nas Escobar Posted June 6, 2017 Report Posted June 6, 2017 You have a couple threads basically asking "what can I put into my GP". It's not redundant, but I can see where he's coming from, especially after I told you in another thread that the LH0 would bolt right in where a LB6 resided. Engine VIN "T" is basically the LH0. 1989 Pontiac Se 1 Quote
