all I have seen have been advanced

Do you mean camshaft advanced in relation to crank or crank advanced in relation to cams

cam shafts advanced in relation to crank

I guess it is also possible that when Ford documented that both cams were out by two teeth, they were counting the teeth on the crank which relates to double at the cams or maybe they just miscounted or even lied, but its impossible to deny that the dents on these pistons were from that previous timing issue as the motor has not been touched since. When I get the car back I will reassemble the head lock the lifters (any ideas on how to do this) and try the timing at several different positions with some wax on the pistons

is there a common compression reading these cars get in good health mick? I'm curious/paranoid now so maybe I'll do a comp test and leak down test on it and see if I get anything

off hand the compressions we see on my gauge are normally 190-200 psi

The next question is ...... what mods can be done to the engine to prevent the chain skipping teeth.

off hand the compressions we see on my gauge are normally 190-200 psi

Had any cars read 200 across the board and then come up with any issues with a leak down test?? Trying to sort out my low vacuum issue but car reads fine compression wise, would a leak down test show anything??

not on one of these cars, but a leak down test is normally more accurate indicator of what is going on

Ok cool, gunna throw some nulon or Subaru upper engine cleaner through incase its a stuck/sticky valve and hoping it fixes it..... Don't like my chances but cheap test.
