UPDATE


After doing 7 days in a row at work I finally had a day off... wooooo! So I got cracking. Thought I'd give the hydraulic tappets a crack and see if I could clean them and unstick the seized ones.


So here we have one seized hydraulic tappet. A couple firm whacks against a firm surface, a quick jiggle and pull removes the centre part of the tappet and we now have two pieces



I assumed that cleaning it as it stood would solve the seized-ness (as some people don't go all the way to remove the smaller section into it's separate parts) but it still wouldn't compress. So no choice but to go ahead and crack open the little tappet. I personally used a small precise flat blade screwdriver to carefully prise off the retaining ring (it simply clips on to the body of the tappet).



Once carefully removed we now have the outer sleeve, inner sleeve with the ball bearing, spring and retaining clip.


Everything seemed ok but there was a bit of gunky oil with slight deposits. The oil was blacker than black though. Gave the bits a good clean allowing them to soak in some meth spirit and a blast of carb cleaner to remove the gunk. After a wipe with a clean cloth and left to dry for a mo, I was left with the bits looking like this



So fresh and clean!

Then it was back to re-assembly. Got out some part empty oil, in this case some fully synthetic Mobil 1 SuperSyn stuff and literally put a drop of oil into the outer sleeve. I then put the spring on to the inner sleeve (sits on the bearing assembly) and slotted the bits into each other. The trick here is to only put a drop of oil as too much oil into the sleeve won't allow it to fully compress and therefore will feel seized and/or really stiff.

Once slotted back I put on the retaining ring and firmly pushed down to lock the ring in place. I then put a couple drops of oil into the larger half of the tappet and pushed the smaller bit into it. One fully working tappet all clean and compresses fine. Two cleaned ones together



I then did the other six and thought I'd leave it for now as my fingers were aching . Once I had one row of tappets sorted I put them into a clean container and filler it up with some more oil and will leave them in there until the head is rebuilt.


Next up is to do the remaining eight. May stick this up in Articles for reference.

UPDATE

No biggie, just an update for the record.

Managed to have a bit of free time after work while dinner was on the go. Got the remaining eight tappets cleaned, re-assembled and in a container full of oil.



Also managed to clean up the camshaft nuts and washers as they were filthy too. They used to be black but now look more like this

UPDATE

It's been another while since the last update

I went on holiday for 3 and a half weeks and come back on Friday. Went to work the next day... and Sunday and Monday and today Good thing though is that I have 2 weeks off due to a refurb whooo.

This arrived the other day, needs a good clean but it's perfect otherwise.


Need to take the crank to be checked, the block to be cleaned and the head to be checked and/or skimmed.

Plan to do this this week... we'll see how it goes

[nova_niek]

Excellent tappet cleanup how-to!

[Nova_Tek]

UPDATE

Spoke to a couple places yesterday about getting the crank, head and block checked/tested/measured.

Dropped off the bits to them today and should be getting a call in the coming days to see if al is well (fingers crossed).

Deffo know they'll turn round and say the crank needs a re-grind just hope nothing terrible is found. Hate waiting to hear news, always have bad feelings

Hope they dont need much doing... Glad to see your still cracking on.
