Wonder if my 3.0l still produces anywhere near 200bhp after 11yrs/150k

Ok, all the valves lapped in nicely, the exhaust ones took a bit more doing (they often do due to running hotter) but, nothing more than a dab of fine paste required!

A shot of the seat following lapping, checking carefuly to ensure the valve seat and valve have nice solid consitent lapping marks!

A shot of the spring assembly, this consists of

1) A metal washer which sits between the base of the valve spring and the head (this MUST be fitted before the stem seals!)

2) The valve spring, these are the same on inlet and exhaust so no worries about mixing them up

3) The valve cap

4) A pair of multi ribbed collets

Next its time to fit the stem seals, I fit these with the valves in place as it makes it much easier to align and fit. A deep 10mm socket on an extension is perfect for pressing these into place.

Valve spring compressor fitted and the collets are going in. I use a small flat blade screwdriver that has been magnetised plus a dab of grease on the collet to make it stick nicely to the valve stem.

Re-fit the t-vents.....note there are two types of these. A version with a single drilling in the side which was used on the earlier pre 98 engines with the early oil pump and a later version with two drillings used with the later uprated oil pump. These effectively control the oil flow to the cam bearings and lifters.

A quick pic of the assembled head.

Thise shiney heat sheilds will give Mick something to think about when cleaning it! Grin

Mar 2009 at 22:40 I should add, if anybody wants me to photo any particular areas of the engine etc whilst its in bits then let me know and I will see what I can do! My photobucket account is certainly filing up quick at the moment! I am also hoping to try to build a head re-furb guide with some of the pics so feedback is appreciated

Will Geff have ideas of what range of engine numbers they fell in??
