Hi guys. Does anyone know if it is possible to remove the cylinder head on the 8v engine in the Sprint with the engine still in place or is it going to be a full engine out job? The reason I am asking is that I may have a failing inlet valve on cylinder 3 but I have yet to do a compression test to confirm that the valve is at fault.
I have a complete guide of cambelt change . Yes , you only have to remove radiator in order to have access to cam belts covers and most important , tensioner and water pump.
Mentioning water pump , it would be a recommending thing to change it with a new one , especially one with metallic parts for better performance but...... If it has never been changed , it will be probably stuck on the block and will require quite a hammering to get her out.
If a job can be done without taking something off, I usually go for that option and struggle a little bit. I always worry about removing something and it snapping, bolts, hose clips, small top rad pipe connector on the rad, rad falling apart lol.
Be prepaired and have spare items to hand
Yes I will be removing the whole unit (camshaft support and head) and taking them inside the house to work on them.
wifey will love that and the fact we won't have transportation for some time. ohh I'm in the dog house now for sure.
Do you know how long the head bolts are?
Also in the manual it says for reassemble that you must tighten the bolts to the specified torque, run the engine to operating temp until the fan kicks in, loosen the nuts, lubricate and retighten.
By how much do I loosen them? Half a turn?? Doesn't specify. How do i lubricate them if I don't remove them. Bit strange.
Yes I have a whole new gasket and oil ring kit.
The head gaskets have the metal rings. Never seen this before.
p.s (moderators) should I start my own new thread as a project when I begin removing my heads with photos or just continue with Mark's thread here?
When reassembling the final tightening torque usually need to be reached
in three steps. Between these steps the head bolts aren't need to be loosened.
The final tightening torque may be different from the factory recommendation,
check the gasket manufacturer's recommendation.
As i know the loosen (1/8 to 1/4 turns) and retighten procedure is required after
the first 500 to 1500 km (only once). Lubrication is not necessarily needed.
