My engine 1296 Spit MK3 1970 is now in the car and is leaking oil from front, one bolt has stripped hole (in the aluminum filler block). The bolt has about only 1/2 inches thread long with the lock washer on, and the bolt hole is about 9/16 inches deep, now if I install and Heli- Coil, after drilling the proper size for the special tap, now that particular tap will hit the bottom of the hole with the bottom of the hole not fully thread considering the end of the tap is taper. I understand that the hole bottom should be close (not drill through) so the oil will not pass through and leak by the thread. Can someone reassure me that this is the way to go? The original bolt is fine thread; the new bolt will be coarse thread 5/16-18 I always thought that coarse thread would be better in aluminum. Am I right? I am also considering installing a new aluminum block, so when removing the old aluminum block will it be critical? I am aware that the gasket under the timing chain cover is adjacent to the aluminum block.??? Also when removing the oil sump can it be done without lifting the engine (All engine accessories are install) assuming that the crankshaft is properly adjusted to clear the oil sump. Will the downward oil pump pipe could be a problem when removing the sump. Any comments or advice will be very well appreciated Thank you, and all of you have a very nice day
