Head Assembly

[xsv_32]

Finally got the R32 25de head back from Cylinder Head Specialists and its almost time to put it onto the block.

BUT it's not at 1tdc and I dont have a workshop manual. Does anyone have a link or an answer to setting the shafts plus angle sensor up correctly? I know the timing is about 15 degrees before tdc on idle but its not ready to start yet and i dont want any bent valves or teeth marks in this pistons!

Any help would be awesome.

Cheers in advance.

Mint i think so. So those cam positions are for 1TDC?

Are there any marks on the backing plate to look for?

Thanks.

When you put the cam gears on, they'll have a marking on them that will align to the backing plate.

Set them to that.

Then, the crank pulley as a mark on it, that aligns to a notch, align it to that.

Put the timing belt on, crank motor over 2 full turns of the crank by hand, inspect these 3 markings still align properly. If they don't redo them.

Mint. Thanks for that, the guy i bought the hear off has left white marks that look like th 15 degrees. Will clean them off and see if theres a mark underneath them.

One last thing, my head gasket is for a GTR, 87mm bore and 1.3mm thick. Everything lined up except for the triangle shaped water galleries between each cylinder on the intake side. the gasket has circles instead but dont think this will efect anything.????
