So I'm tired of tearing this car down repeatedly....
First, I blew a metal AJUSA head gasket in June at the drag strip, and installed a new FelPro head gasket, and car ran fine for a week or so....(i didnt have the block decked when I rebuilt it)
After a week or so, I developed a coolant leak it seemed between 2nd and 3rd runner on intake manifold. But on the bottom where its very hard to see. It would run down beside that small freeze plug right above where the balance shaft cover is, and then drip onto starter, and then onto the ground....
So 2 weeks ago, I took intake manifold off and cleaned off all the old gasket because I had used a gasket and gasket sealer. (When I first cranked the engine 2 years ago, it leaked from intake manifold, and I removed it and saw it needed resurfacing. So I paid $25 and had it resurfaced, and it looked perfect. I didnt have any leaks at all up until now). So after cleaning and scraping the surface and using a dremel with a small polish brush, I had it very smooth and clean.
So yesterday, I installed a new Felpro gasket and got everything back together. The car ran fine, and still had a very tiny leak still but it wasnt running down, so it was a very slow leak.
I take the car for a drive today, to check for leak again, and I saw it overheating to 220+ so I pull over. I pop the hood and its spraying coolant from that spot under the intake manifold. I can hear it sizzling and everything is wet.
Does this sound like I need to try another intake manifold? This may be a dumb question, but could it actually be leaking between the head and block? There is a water jacket right near there...Or could the head need resurfacing? This was a new NJV head from DAD. Everything has less than 3k miles on it....
As for the intake manifold, from the first resurfacing, it seems I shouldn't have it resurfaced again. It did take a good bit of metal away.
I'm tired of taking this motor apart....
Can anyone give me some insight?
Thank you.
Mark
