Hi Guys

Could this be a hydraulic tappet problem, not lifting a valve enough?

Just a thought.

john

is it noisy then?
like TACK TACK TACK noise

that's a loud noise...

Those compression figures are dreamy for an Aircooled engine... very healthy

yes kev

does it disappear after a good long drive?

I dont really know kev, last time i took her out I couldn't get over 30mph!

the chap seems louder at times then other times its not so loud.
She did run very low on oil just before this happend!

the lifters have drained ....it needs to be driven for a while to fill them back up
Don't worry you won't do any damage but take it fairly easy

all thats happening is the valve(s) affected wont open completely and the open time is ever so slightly affected.
It won't cause the popping.

Cheers Kev, mega flat spot the last time i had her out and no more than 30mph like i said.

I will take her for a run and see what happens.
Still need to get to the bottom of the popping then?

Kev spot on mate, took her for a drive and all is good now

I still have a small popping when going down hill and changing from 4th to 3rd on over run.
Im thinking exhaust issue poss.

Anyway thank you all very much for all the help on this issue.

Lesson learned keep an eye on oil level more regularly.

MOT next week so fingers crossed!

Much appreciated

John

you still have that air leak in the manifold too

We cant have everything Kev, she is running good enough for now.
I dont fancy taking the manifold off just now, winter may be.

Thanks again mate
