Shims???????????

[gtir_2007]

thats cool. I wasnt slagging it off by the way. just mearly pointing it out. If its definately the shims I'll just go with your idea i think. Seems an ok option. I spoken to my mate since and he says that it could be the lifters as it comes from the front and back of the head, whereas if it was the shims it would be the centre?

Does this make sense or shed any light on the subject??:sad:

could be either shims or worn rockers / cams, as they are at the front and back.
dont know where he got the centre bit from:?
tbh you wont really know for sure untill the rocker covers removed and you looky see for signs of obvious problems, and check over a few things!

OK thanks. I take it if it was lifters/shims there would be some scouring?

Apart from shims and the cams is everthing else available easily from nissan? thanks

why are the shims so hard to get from nissan?do you already come shimed in size from them?

If you're taking off the rocker cover remove the oil pipes and check that they're still clear and not blocked....

You just have to measure the clearances and then work out what you can use from what shims you already have then re-order extra sizes he should be able to measure them up in no time ;-)
