naviathan Posted April 13, 2008 Share Posted April 13, 2008 The only gasket you can reuse is the MLS style gasket (Multi-Layer Steel). The stock felpro type tend to fall apart when you pull the head off so I doubt he reused the gasket. If you just swapped in new pistons, wouldn't you have changed the head gasket out? Also if it was a high comp engine, how high? What compression ratio are we talking here and what type of fuel were you putting in it? All this can contribute to a blown head gasket.

Wedge Posted April 13, 2008 Author Share Posted April 13, 2008 12:1 compression the previous owner did the work and i used premium ,here max octane is 91 ... Well if i have to put more then 500 $ on it its gonna wait i was goin for the RB swap anyway . Thanks guys . Quote Link to comment Share on other sites More sharing options...
naviathan Posted April 13, 2008 Share Posted April 13, 2008 12:1? On regular 91 Octane pump gas? No wonder it blew, probably pinging like crazy. For that kind of compression ratio you really need to look at race fuels for any kind of reliability. Quote Link to comment Share on other sites More sharing options...

Thanks guys . well if you going for the RB swop then obviously forget my last post with regards to the engineering etc... Did you drive it before it blew?

Wedge Posted April 13, 2008 Author Share Posted April 13, 2008 Sorry took my papers out to be sure and compression is 11,5:1 still Very high . Ok then ill stop putting time on it and start thinking to what i will do . Thank you guys . Quote Link to comment Share on other sites More sharing options...
Wedge Posted April 14, 2008 Author Share Posted April 14, 2008 One question id like to ask if i put all back together and drive it like a grand'pa will blow again right away or ill be able to drive it around a bit ? My quest is yes but for how long . Quote Link to comment Share on other sites More sharing options...
cockerstar Posted April 14, 2008 Share Posted April 14, 2008 If you put it all back together and get some good gas to see if anything else is wrong, I'm assuming that you could sell it off to someone to help finance your RB swap. Even more so if you were to get it dynoed for the sake of having numbers and a curve to show what they're getting. Quote Link to comment Share on other sites More sharing options...
nick.mitchell69 Posted April 14, 2008 Share Posted April 14, 2008 If you dont skim both surfaces,chances are it will pretty soonish...even snailing it i reckon a week or two before the symptoms arise once more Quote Link to comment Share on other sites More sharing options...
Wedge Posted April 14, 2008 Author Share Posted April 14, 2008 Well ok then , thanks Nick for the advise its very appreciated . Quote Link to comment Share on other sites More sharing options...
Wedge Posted April 15, 2008 Author Share Posted April 15, 2008 I checked out the file the previous owner had and when he had the motor rebuild he had the head sonic tested and rebuild completely so at least i can delete the water passage break up in the head . Im going today to check the thermostat and water pump that were changed in Nov. 2000 maybe ill see something thier . Ill check with a filler gauge if the head and bloc are in spec tolerance .

nick.mitchell69 Posted April 15, 2008 Share Posted April 15, 2008 Check the radiator cap too,could also be a small contributing factor. Check what pressure it can handle,the lower the pressure,the faster it will cook.With TDC,the crank pulley mark is on 0,the cam sprocket usually has a groove behin the number 2 which should line up with the little hole in the cam... Ring any bells...? Quote Link to comment Share on other sites More sharing options...
Wedge Posted April 16, 2008 Author Share Posted April 16, 2008 Yes it rings a bell . I finally decided to stop all efforts after i tried to put the cam sprocket back on the cam i took the piece of wood i had to keep the tensiner in when i tool it out the tensioner fell . So i give up im starting to dismentel it and sell the parts . Quote Link to comment Share on other sites More sharing options...
nick.mitchell69 Posted April 16, 2008 Share Posted April 16, 2008 Unlucky man,that happened to me over Christmas last year,had to take the timing chain cover off to put it back in.Only cost me a day of working on it though... Quote Link to comment Share on other sites More sharing options...
naviathan Posted April 16, 2008 Share Posted April 16, 2008 I did the same thing except I used the timing chain tool from MSA. It's a waste of money trust me. I ended up pulling the radiator, sway bar, oil pump, front cover, etc... and putting the tensioner back together. It took 6 hours to get the cam sprocket on because of that one little chain tensioner. Quote Link to comment Share on other sites More sharing options...
