Strap him (or should i say child seat), you can have a 3 seater and all go out......

Are you up for track time tomorrow night Mark?

Sure you've put in lots of good behavior....

Hi Andy,

The followers are a little on the loose side in fact quite loose especially if rocked side to side. The hydraulic tappet pumps up with oil pressure so they should stay quiet when running but if they get crud inside then they either don't stay pumped up during the valve closed phase (lazy tappet) or they stay deflated (collapsed tappet) during valve lift, often accompanied buy a partial misfire. When collapsed the noise sounds deeper like a big end but faster if you get what I mean.
A lazy tappet might be revived but a collapsed tappet should be replaced imediately as it could spit out the follower causing a lot more damage.

For Info the engine oil supplied by Ford for engine testing and development when these were 'new' was Motorcraft 15w40.
Now they use 0w20 how times have changed.....

As for the Pierberg carb, the problems are with the choke system. Bin the choke flap and the module that operates it unless your using the roadster in the middle of winter.

andy you had the hyd tappets out? im pritty sure you can fit them in the wrong way on a 1.8 cvh so the oil fill hole doesent line up.
you did put them all back in the holes thay came from? or did thay get mixed up

shouldnt take to long to whip of the rocker cover remove all the rocker arms and take out the tappets for a looky check the rollers on the bottom, oil holes, look down the tappet tubes to see if the cam is worn etc. even a oil wash out in the pariffin bath sometimes clears the sludge out and revives them.
failing that new tappets it is

too thick oil is just no good for hyd tappet engines as thay require a bit of leak by to lubricate and ajust corectly back in the early 90's i used to get engines running the cheap 20/50 5haging the cam lobes as the tappets failed to ajust going too tight and braking the hard skin on the cam all from the cost of a few quid on some oil
10/40 should be ok any lower could be a little thin for an engine of the cvh design era as thinner oils came later

My pinto sounded tappety when she had been stood a long time. Took her out for a good thrash soon sorted it out. Change the oil put some cheap 10/40 in fit prop give her a good rag up and down the road let it idle til the fan kicks in then see if its still tapping. If not put good oil in if tapping rag it some more. If it gets worse after a rag call it a day and swap the engine its the cheaper option.

Ash's point on swappng the engine may be a good one...

I had spent about £150 excluding the cam on my 1.8lx before I swapped in a better unit. the cam was £100 too!

You could just find a good runner and swap the heads over.


One final thought, have you got that oil guage on yet ?
