Hello all.

Quick question.

I'm having trouble with my tappets. I seem to be having to adjust number 4 & 5, every couple of weeks for no good reason. 

I have read the guides on here and am confident i do them right each time, i check the others each time and are always fine. 

The springs can be compressed fairly easily using my thumb on these two tappets, which surely cant be good? 

So any advice on what to do would be good!

Sick of driving on two cylinders! 

 

I do roughly 200 miles a week, 

Engine is a 998

It's a 81 HL 

Its leaded, but i use the additive

 

Cheers!

Gap widens or closes?

Yes, could be the rocker pads worn giving fake adjustment

Widens. Massively.

So a new set of rockers and springs, should be merry?

Could be really worn pads. Try to widen tappets gap as much as possible, so you can see between pads and valves. If you see a deep groove where the pads meet the valves, they should be replaced.

You can also replace just the pads and the shaft.

Cant comment on the springs without seeing them..anyway the std 998 spring are very low pundage, about 60 lbs iirc

is there a guide on the forum somewhere concerning tappets eg exactly what they do how they affect the car and how to replace / repair adjust them?
