Tappet adjusment - Sorted

[Chaz23]

Right I am about to adjust the tappets on my X/Flow but the instructions in the manual are rubbish.

 

Now normally I would do something like this with my Dad's help but he is on holiday, no problem I thought but how wrong am I. OK I understand that I need to check the clearance (not a problem) for each valve when a particular valve is in a particular position (OK so far).

 

But how do I move the engine round to move the valves?

First take the spark plugs out to remove compression as an issue.

 

I normally just use a spanner on the crankshaft pulley, making sure you turn the spanner in a way to tighten the bolt up, rather than loosen it.

Or you can just put the car in top gear and pull it along the ground to turn the engine.

Many thanks for that all sorted now one or two where slightly out.

Can you tell me what you gapped them at please.

[Roger King]

Gap depends on cam profile so there is no general answer. For example, a standard 1600GT cam has gaps of .014" inlet and .021" exhaust, whereas a Supersprint cam runs .022" inlet and .024" exhaust.

 

Don't get too finicky about this. There is so much slop and bending in Crossflow valve gear that a variation of a couple of thou or so will make no practical difference. OHC engines with tappet pistons are far more precise.

Thankyou very much for the info roger,you are the crossflow king !
