Thread: 95 GTP 3.4 oil leak and antifreeze leak. Need help

as for the oil, these engines are common for the Oring leak just under the tb on the block. it has a plug that was designed to fill the spot for a distributor. the o ring fails and it weeps oil. some people clean it and use RTV but that doesnt last for more then a year. believe me i did it twice. on the third time i was done messing around. I got some QuickSteel epoxi and packed it in there after removing the bolt and cleaning a mating surface. let it cure and its done. I wouldnt use JB weld as it is too runny and could seep down and glue something that shouldnt be. the epoxi fix never leaked again. I had that engine for another 4-5 years before it died and i did my l36 swap.

sorry had been busy. to get at this plug the Lower intake needs to come off as it is bellow it. some people grind a little bit (1/2 inch) of metal off the head thread boss that is directly above the plug to make more room for it to come up. I took only about 1/4 inch off as i first tried to RTV it. I would get a bunch of shop towels and degreeser to clean it all before you use the epoxi. as for the coolant leak, rent a coolant psi tester and pressurize the system and you might even be able to hear the leak/ hiss.
