I took my car for an MOT recently and suspected that it wouldn’t pass as all the lights were on the dashboard, as they have been intermittently since I bought the car. I have long suspected that this is a mechanical issues as the car is very tappety. Sure enough, the car failed and a chap specialising in diagnostics confirmed it was likely to be a valve issue due to it having low compression on one cylinder.
So, I decided to do the tappets. This involved removing the poly v belt, timing belt and cam cover. Having got to the tappets, it was obvious that 3 had failed completely as they were not holding any oil at pressure. Alarmingly, the whole area was also covered in a black paste, probably the result of a lack of regular oil changes in the past. No wonder the hydraulic tappets had failed.
Having got this far, I was in two minds whether or not to pull the head off and check the valves too. In for a penny, in for a pound, I removed the inlet and exhaust manifolds, thermostat housing and removed the head. I’ve taken that to a local engine reconditioner, to have the valve seats reground, new valve seals and the head faced.
I’ll let you know when it’s all back together whether this has cured the intermittent mis fire and low manifold pressure which have been problematic for a long time. Fingers crossed, otherwise it might be up for sale!
