Ok so I have been working on a 394 xp. It came in with a bog. Did all the easy stuff including a coil and didn’t fix it. I blocked everything off and did a pressure test. All seals passed but intake didn’t. I had bubbles. I pulled intake and found plastic cracked. Figured as it got warm it opened up. I replaced it also added a new gasket. It runs great until it gets warm and then leaks at the gasket. I took it all apart and added some gasket sealer and let it sit for 4 days. I started it and ran it today. It ran good until warm and then bogged again. I pressure tested it again and bam gasket leaking again.
