T25 Compression Low

I see you already have sprung tubes. That looks worn to me, but I doubt there's 1/4" worn off it! If you have more sprung tubes maybe fish out a good one and compare?

 

I'd also compare pushrod lengths.

 

Yeah I have no more of them. It still looks like a milled end ie with the round markings but that could be down to cam wear. The cam end is very shiny. I have put it back in for now run out of time. Although I managed to adjust the tappet enough now.

 

I have compared pushrod. They are same.

 

The cam end should be shiney and smooth and very slightly radiused.
I'm baffled that you managed to set the tappet unless it was slightly on cam i.e. engine in the wrong position, or you didn't have the rod in the cup of the follower.

 

The rod is now in the cup. But if I can't even get it started I'm still no better off. I must have messed up the settings on the tappets. I have redone this twice and still nothing. Stick to my day job eh!

 

You need a fresh pair of eyes on it.

 

Was it running when you got it? I'm thinking someone's put non hydraulic followers in to save money maybe ? If the followers are approx 8mm shorter then longer non hydraulic pushrods could fix it, or new hydraulic lifters, check how many are non hydraulic, you can look through the pushrods tubes from
The top to see, non hydraulic are plain, hydraulic have a few components and a clip holding it together

 

It was a non runner due to perished fuel line. But I had it running the second we got it back.

 

How well though? I had on running with all knackered followers, sweet revving with no load, rubbish under load, the rocker arms as with yours ran out of adjustment, new followers and it was sweeeettt as a temp measure you could try the locknuts on the bottom side of the rockets

 

Where can I find these rockets and do they make it go faster?

Kev the rev has it the wrong way round, ali rods for solid lifters, steel for hydraulic.

 

There's so much info flying about its boggling

 

You have something of greater value ,experience...

 

Time for a strip down dude... Plane and simple!!

Someone has put new lifters on an old cam and that'll have de-lobed it... Hence the adjustment issues

 

What does De lobe mean

 

I wouldn't strip it assuming cam de-lobe, how would he check cam de-lobe

 

the lobes on the cam get worn away and are no longer a teardrop or egg (roughly) type shape. means you dont get the lift

 

Worn out cam, but it's only a possible not a certainty, if you do a couple of things and tell me the outcome I can tell you what the problem is, but I can tell you now those followers are t standard, the pushrods sit inside them, measure the drop from the top edge to the bottom of the inside of the cam follower, what is the length ?

Put a follower back in and put a pushrod in, turn the engine to top dead centre, how high is the pushrod? Now turn to bottom dead centre what the height now ?

You need to find what's right before deciding what's wrong.

After that I would be trying a hydraulic follower and see if the gap issue goes away
