I purchased a 1.4L Ford focus a few days ago for my sister, put an MOT on it, needed a new bush, which i did first, then serviced it, polished, with a full valet, then i went to do the cambelt.... (did it at work in the workshop where i had all the correct kit)
Timed it all up with the locking pins (has free floating crank pulley) fitted a gates cambelt kit, then refitted the bottom bolt and pulley aux belt pulley with the original bolt (only supposed to be used once), fired her up, lovely all good! So i remove the bottom pulley again, to fit the covers, this time i use the new bolt which came with the kit, started it again... spluttered, died, then i cranked it... loss of compression... surly not, couldn't have.... checked it over, timing was spot on as per the marks i made, but when fitting the locking kit blow me, the timing had slipped right out and done every bloody valve!
Turns out the gates kit came with a new bolt which was far to long, i assumed (after confirming it was the correct kit with the supplier and on the sticker on the box) the bolt was longer as the result of a known issue (as the tensioner was also changed due to past issues) it didn't compress the free floating bottom pulley the thread hit the end of the hole causing it to slip .....destroying the engine
Very very teasey!!!
