I have an S2 Rs turbo as a project which im slowely sorting out. I managed to get it running but it was misfiring and very noisy.

I thought I would take out the cam followers and put them in the vice to clear them out. When I got to the inlet follower on cylinder 2 I noticed the bottom of it is very worn. Is this normal wear and tear or has something caused this. The lobe on the cam is worn as well so will have to get the head off and replace cam and followers etc.

Hi

Normal wear and tear. No need to remove the head, cam slides out towards the passenger side of the engine bay after removing the dizzy, cam whell and thrust bearing. If the followers will not pull up then move them down into the space were the cam was (aftet you have removed the cam of course). If you pull up a worn follower you will likely scratch up the follwoers housing so oil pressure will be poor to that follwoer causing issues.

use good quality parts and rmemeber to follow the running in procedure - usually a case of not letting the engine idle for half an hour or something like that whilest varying the revs to different levels for that time

Thats good then, it shouldnt be to serious then. Thanks very much for the advice.

What cam and followers would you recommend? Im not going big power, would like a bit more than standard but want it reliable. (as reliable you can get from a Ford & MFI!!)

Standard cams are good if your not going for huge power mate

Standard as in genuine ford or is aftermarket OE stuff ok?

I have just chucked in a used set of followers out of an xr3 head I had, it runs a lot better. I was planning to strip the complete engine soon so might as well replace it all in one go.
The shopping list just keeps on growing!!

the std spec cam is a very good balance between drivabilty and hp. will comfortabley cope with well over 200hp before its at its limit, 250hp seems a familiar figure. my car runs a .48 t3 and works well with the oe cam. makes good torque from 3k upwards with no major lag. i think when the time comes you ought to change cam AND followers together as they need running in together. in fact, the mfi will be at its limits long before the head/cam/inlet ect. there fairly reliable up to about 200hp, on mfi going much more is a gamble as the fuelling is a guessing game. 5th injectors are a good mod at this stage.

Yes I will replace both together, I was just intending to get the car on the road, use it for 6 months say then strip engine and rebuild it, oh well.

Around 200bhp would be a nice figure I recon. So might as well stick with a standard cam & followers.

Thanks very much.

200hp is properly quick and useable. i think spinning the wheels in 4th as the 300hp guys do must get tedious after the novelty wears off. would be nice but 300hp+ costs big money from a cvh.

There is gonna be one shitload of swarf floating round your engine right now

P 17eed

Surely if this is just general wear then it's been leaving bits of swarf since day 1.

mgtkr1

might be worth oil/filter change. i change filter with oil every 3k. for the cost of a filter, daft not too.

haz87

I personally wouldnt call the above picture 'general wear'. Thats worn really badly. The one on the left is general wear.
But yes, whenever that lobe/lifter started doing that you will have been circulating swarf. Unfortunately CVH's are crap at filtering out swarf and seem to enjoy putting it through ever bearing and journal before eventually getting caught in the filter
Id definitly do an oil change and get a magnetic sump plug to see if you can catch anything floating still (it wont all come out in an oil change annoyingly)

P 17eed

Yes good point. I will do that. It's not likely to see the road anytime soon still.
Still a bit more welding then prep, paint and rebuild to go!!

That is certainly way more than normal wear. There is a significant portion of the lifter "missing". There will be a significant part of the camshaft lobe "missing" as well.

You are taking a HUGE risk just doing an oil change and replacing the cam and lifters.
All oil passages require cleaning - removal of oil gallery pipe plugs and thorough cleaning of all oil passages (even crankshaft ). You are playing Russian Roulette if you don't clean out every oil gallery (cylinder head included).

P 17eed

It will be stripped and rebuilt before seeing the road. I built it back up today and fitted a Bailey breather, the system was under a lot of pressure. So it's defiantly rebuild time.

Canada1

Full rebuild time is a good decision - and will save money in the long run.
You should post some pics of the rebuild.

Cheers
