Can anybody recommend were to obtain a new set of tappets for my 1976 2.25 diesel. The ones in are pitted and it's hard to set the gap correctly.
 
Hi, yes rocker arm sorry, I don't suppose you can have them re engineered the hardened surface has pitted, l suppose I'll have to bite the bullet and replace them. Thank you.

You might, but at a twelve quid a time for new, I doubt of it's worth it.
 
I just got the oil stone out and did my own....quite some years ago with a 2.25d....still going strong years later....you have nothing to loose.

How bad are they...mine prob had a 15thou indentation off the valve head.

I was thinking that I might be able to reprofile them but I wasn't sure how hard the material under the hardened surface was, certainly worth looking into after seeing the price of new ones!

you can grind a new surface on the rocker and fit valve stem caps which increases surface area rocker pushes on so reducing the pocketing in future, there are machines reconditioners use but you can do it free hand with a fine wheel with a steady hand
 
Did it on a Mini head many years ago. Used a small piece of mild steel as a block and ever decreasing wet and dry. Finished with Brasso.
Worked a treat.
Takes for ever though. I dont think Id trust myself with a wheel no matter how fine. I would however start with a fine diamond sharpening stone if I was to have a go now. Mostly because I have one but they are not that expensive these days for a good one.
 
I don't know how much a set of rockers cost but if you consider how much time and effort it would take to grind them properly yourself, it must surely be cheaper to buy new ones, unless you are a skilled machinist with access to the right kit.

That was my reasoning also. Under a ton for a whole new set. And probably saves a couple of hours work. And you have new, instead of ground down old ones.
 
You could always buy several new cylinder heads and take a photo of them with your swimming pool in the background. :D

Didn't seem particularly hard from what I remember when I did mine.

How good are the new ones we must ask....like all the crappy pattern part we have to put up with.

Go for it.
 
If the oil stone is very slow have you got a bench grinder....it was a long time ago I did mine...maybe I took the heavy stuff of first and finished with an oil stone?
