4.6 head gaskets and cam / lifters

As I feared!

Yep, will definitely go the top hat liner route, but its for this reason I have to get it on the road now - can't do the liners at this point in time.

I'd planned to measure lift at all the lifters to ascertain cam wear - I did about two and stopped when I noticed one lobe on the blown gasket cylinder had lost about 2mm. I have seen much worse but upon purchase I was convinced the noise was a lifter (though it turns out it was likely the compression leakage). It'd suck to put the heads on and find the lifter was actually noisy.

If you need to get the car back on the road then one of those should last at least 10,000 KM [biggrin]

I would not put a britpart one in my rebuilt engine however

Good luck

The hydraulic lifters in these beasts have pretty wide tolerances and usually rattle a little until they get their act together. Once you get the heads back on there is a procedure for checking the lifter preload. You can put shims in the rocker train if it needs adjusting
