Thanks for all the info. All rebuilt now engine running okish have a slight tappety noise I guess I should have changed the cam follower buckets. Also seems to lack a bit of power. Just nipping around low speed roads feels fine but went onto the dual carriageway last night and car starts to slow down on uphill sections won't hold 70 mph even on slight inclines. It is like there is no boost or lack of fuel. I am wondering if I have put one of the vacuum pipes on the wrong place. Would this cause the problem or is it something more. So want to get this right it's a lovely car to drive. Cheers
