Hydraulic Tappets that have been Adjusted ?!!?!?!
Discussion
Help needed?
I rebuilt the top engine of my engine about 300 miles ago. When the engine was installed the tappets were adjusted.
I believe the engine has hydraulic tappets, so should not have been be adjusted, now the tappets are a bit noisy.
What do I need to do to correct the situation?

Sorry, I cant answer your question,I have had a good look on the following site which has some good info (pdf s) on the engine but it appears only to warn not to adjust for any reason, you may find something if you go through them all, I suppose they're worth having for ref on other jobs.

It would be very much appreciated if you could find it, they don't sound too bad, but do need fixing.
Thanks for all the help.

Found this on the TVR Owners Club website. Does this make sense?
My car has a Chassis number before the one quoted, i.e. last five digits 11223, so this must have hydraulic lifters ?
I'm getting all confused !!!

I had the same problem as you - I set them but didn't know they were hydraulic, and had to fix it.
How did you know that this had happened, was it really obvious, mine are noisier than they probably should be and I do have a small amount of irregular idling, which could be due to incorrect valve clearances?
The noise also varies, which makes me think they could be hydraulic and are adjusting them selves incorrectly?
Really don't want to sprip the engine down

Does anybody have any pictures of a solid and hydraulic lifter?
Here's a picture of the top of a hydraulic lifter for the RV8, from the RPI V8 web site:
www.rpiv8.com/images/Tappets_Meauring_preload.jpg
The basic principle will be the same; looking at the end where the pushrod end sits, you'll see the open end of a sleeve, with the top of a moving piston inside it, and a retaining clip stopping the piston from coming out. If you have solid lifters then instead of this lot you'll have a simple bucket that the pushrod end sits in.
I have now taken off the rocker covers and you can see the top of the hydraulic lifter on some of the push rods. I have also taken an old 2.9 engine apart to see what an old lifter looks like, they do not have the retaining clip as above.
Sooo - you can tell the difference when you take the rocker covers off, correct?
