Thank You Jerryjerry05
when taking the ports off I noticed that some screws weren’t tightened down all the way; some seemed barely over finger tight. Come to think about it I’ve found striped out screws on the intake. You think there may be a leaky gasket(s) on exhaust side also?
With a head hung low, and hoping im doing things right; I went and got a comp tester from harbor freight and did and got some bad test results after Ive replaced the head gasket(twice; torqued in sequence the second time). Before, the comp test revealed #1 at 85, #2 at 140, #3 at 155 and #4 at 150. NOW, Im getting 60, 60, 120,120...Plus after removing the plugs I noticed a milky/oily mucky substance on 1,2,and 3.
The engine is trying to run but coughs and backfires. I don't know what to do at this point
He said the rings were free when he removed the port covers.
If the screws were loose?? That would cause a lean condition and make it run poor and hot.
"poor" coughing and backfiring.
If the plugs have water or brown sludge the exhaust gasket could be bad???
That's if the head gasket is sealed right.
The exhaust chest:
This is the worst thing to remove from the motor
Usually 2-3 of the bottom screws twist off and can be a B to fix when the block is still on the mid-section.
After the screws are fixed, then the reassembly starts.
I've found that it's best to get the mating surfaces of the exhaust and the cover milled as the
edges have been eaten away(not very thick in some places.
You can try to seal them and might get lucky? I think I got lucky 2 maybe 3 times and had no leaks.
They sell some gaskets for the exhaust that are useless, they are thin and don't work unless you double or triple them.
The thicker ones OEM work best. Gasket 8190242 15$
Get from a good source. They might sell them here.
ebay sells them and they can be cheaper but probably not what you need.?
Some gaskets just don't seal good and silicone is needed no matter how clean the surface is.
Did you compare the old gasket with the new?
They also don't always match right??
When I did a couple of rebuilds I bought a few on eBay, trying to save $$
They didn't fit .
