Hey guys I am working on a 1999 Ford Taurus Se OHV (pushrod engine) its the vulcan 3.0. I am replacing the piston rings in cyl. 1 and 2 since I took the pistons out. I took my car over to mineke to get it fixed and when they checked the car they said that cyl. 1 and 4 had the following pressure to them (cyl. 1 had 61 Lbs per sq. in. and cyl. 4 had 91) everything else was at 110 and 120. I had replaced the head gasket so I ruled that out and also checked the heads and found them NOT warped. I went to Napa for new piston rings and connecting rod bearings and there was a guy that told me the head bolts were bad and needed replacing. I couldent see how this was the problem but decided it wouldent hurt to try it since they werent expensive. I have not put the new piston rings in and torqued all the connecting rods down and what not but not I cant get the oil pan back in the car. I am working on the engine INSIDE the car (figured it wouldent be too bad doing this since it was only going to be a ring job). I need some tips on how to get the gasket back up and in place. I also would like to know if the head bolts could be the problem for the leaks in the cyl. Any information at this time would be great. THANK YOU!
