My 2ltr CU sounds like bag of spanners on start up, like they do, but the sound doesn't die down after a few seconds. I only put it in a few weeks ago as my old CU was down on one cylinder. I changed the oil and filter straight away to straight 30 - as sold and recommended by GSF, JK etc - and it sounded like a bag of spanners. A week later I put 20/50 in, but didn't change the filter, and it now sounds like somebody took a few spanners out of the bag, but still rattly. The oil light flickers for a few seconds after start up, but my old one didn't do this. So, even though the tappets are hydraulic, can they be adjusted, or could it be terminal? It doesn't smoke or anything like that, and hardly drops any oil. It does ever so slighlty get less rattly after a few seconds, but it still rattles like a good un, and also, it's a bit slower than my old one. It'll get to sixty, but it seems to take longer as if it's down on power, thats why I thought it may be the tappets. Any ideas?

have you driven it??
the lifters will repressurise after a good ten min drive or so.

you still have to set the gap on the rockers, but only 1/4 to 1/2 a turn, not as the haynes says 2 turns.......

also you need to make sure its bled up, by driving it, as said above

It's my daily driver. The first week I had it done I went to Anglesey and then last weekend I went to Cardigan Bay. I reckon I've done over a 1000 miles in the last couple of weeks with going to work as well and it's still noisy, as if the oil is low or old. Which it's not. Unless it's disintegrated in less than ten days.
So can you adjust them, even when it's not been rebuilt? I thought hydraulic tappets took away the need for that. It's not a new engine by the way, it's a second hand one, but like I say, it uses hardly any oil compared to my old one and doesn't smoke either.
And has anybody cleaned out that oil strainer thing under the engine? Just wondering if it may be clogged up.

Hi mate.

I had this very problem and followed a lot of advice from some very good people on here.

However after reading this in the wiki (you did check didn't you?) I have not had a problem
