just tried that thread.... i dont have problems with the tubes or seals... my problem is that since i have donr the job the bl**dy thing will not start dosnt fire in anyway at all.. plenty spark at the plugs though so im guessing its a rocker-valve problem!!!! can anyone help????

have you knocked a lead off or something daft like that.Vacuum hose maybe. Best look for the obvious first.
Good luck.

How many turns preload have you put on the adjusters?
haynes is too many for recently run engines.

Sounds like you've done some work, then set them up as new tappets, not pre run ones, so in effect what you have done is jack all the valves open.

Does it spin over really fast? like no compression.

Don't put a CJ in, I've seen a few retro bodges like that and it's not pretty!

if it is a rocker problem then it can only be the valve not opening enough or not closing fully either way ther`d be little or no compression which you should be able to tell by the way it turns over on the starter. if you cant compression test it.

i did as it said in the haynes manual which is 2 turns and yeah it spins real fast!!! i was just joking about the cj although i do like the old cj just finished rebuilding one another 2 to go how many turns should i do on the pre run tappet screws???

I never go more than 1.25 turns.

It will probably run like a pig until it sorts itself out.

ok thanks for the advice.. i will try it tomorrow, i have had enough for today!!!

been at it since half 7 this morning.. tried everything and still would not fire up!! so i took a chance and set the valves for solid lifters 0.006 on the inlets and 0.008 outlets... hey presto she fires up looks like whoever had it before me changed the hydraulic lifters for solids... I will wait for the season to finish then drop the engine out for a full rebuild back to original spec....

That'll be a volkspares engine then.
Right pain in the a*** they are, usually have mexican beetle cams installed so they have even less power than they should.
Is there not any stickers on the rocker covers telling you they are manual tappets?

it does look like a recon and now that you mention it in the paperwork there is a faded or washed receipt that looks like the volksspares logo and i can read bla bla engine replacement bla bla exchange bla bla.. so it could well be one of them... The rocker covers have been changed to aluminium covers....

thats a bummer if it does have mexican beetle cams will change them when i drop it out and rebuild!! but she does pull really well and cruises nicely at 70.....
