saph cos 4x4 oil pump need help asap
aye a thought so, thanks for help again tabetha, dont suppose you no if the dot on the crown of wiseco pistons point towards timing belt or flywheel?? i would of said timing belt end but the spacing of valve cut outs suggests other end. also what do i do with arp stud kit for the head? i have measured and tapped the holes etc, arp says you only put them in hand tight???
Never used wiseco so can't comment, with the arp measure the depth of each bolt hole, and run a tap down them with grease on, and also scrape out the bottom of the holes to get out congealed oil.
On a few occasions the hole depth can be a tad shallow so check the length of the thread part of the stud, and that when fitted it is not bottoming out in the hole, ther eis a shoulder on each stud, this must contact the head, there is a very small recess around each hole for the shoulder to sit on/in.
Put them in had tight, then just a LIGHT nip with grips to ensure they are fully seated, nothing heavy, threads pull out due to stud bottoming not due to tightness, I do mine up in 30lbft increments up to 120lbft, leave at least 4 hours, preferably overnight if you can and retorque the next day.
I use some 10W40 oil just smeared into the threads, not swimming in it!!
