Hi..there..

Depends how bad the camshaft is? if its heavily rusted/ scored and pitted really badly..you'd be best just replacing it.. If its surface rust..you could try using 3M scotchbrite pads and adding light films of oil/wd-40 whislt your rubbing it back...maybe try a very light fine sandpaper/wet and dry..but after which you need to clean it with a parts cleaner..then after which before you install it you'll need to pre-coat the entire cam with engine oil..before install or engine build pre-lube...hope this helps

where can i buy 3 m scotch brite pads and want grit range sand paper do i need
Expert:  Robert replied 6 months ago.

Maybe try online - Amazon / Ebay - maybe have look around B&Q or any local motor factors..one place you might get them or both or similar is local automotive body paint supplier? if you know of one locally who mixes or makes car paints?..1000grit might be better..but try the scotchbrite pads first

photos off subframe im going to paint two coats off hammerite
Expert:  Robert replied 6 months ago.

Yeah Hammerite would be the best stuff to use..usually that paint goes on quite good with 1 coat.but i guess its personal preferance to do it again..

If you have bench grinder with wire wheel you can clean them up.or a wire wheel on a grinder/ fast drill..would work..thena light coating of bearing grease on the splines..and it should be fine..if the secondhand ones look better then just wire bursh them and an light coating a grease on the splines..makes sure the C- clip is free to move on the ends...

Fitted clutch slave cylinder to gearbox ive put l m 2 multi purpose grease on o ring on one side that side ive fitted to gearbox i ve put threadlocker on clutch slave cylinder bolts. On new clutch slave cylinder theres a silver pipe ive took a seal off that and fitted it to ordinary black pipe. Ive fitted black ordinary pipe to new clutch slave cylinder.

Ok.. one of the pics with the bolts - that waaay to much thread locking fluid..you only need a very small amount..besides any slave ive done on these you generally need to put thread lock on them..as long as they are tight..then a slight 1/4 turn..that should it....the large o-ring seal yeah again you dont really need grease on that but as long as its seated then that shoule be fine too.. the other pipes..these just connect together the elbow should have bleed screw on it the clutch hydraulic line..but as long as the pipes are correctly connected and the small clip that between the slave and the hydraulic line is secure.then that should be ok..you'll only know if you have any kinf of leak is wehn you come to to bleed it..but looking at the photos with gearbox still out..you have way to go yet before you reach that point...normally bleeding is kind of the last things to do before the cars started up to ensure the clutch is clearing properly and gears can be selected...

If youve fitted a new clutch slave cylinder and fitted new o ring tighten bolts till tight then if you loosen bolts and take them out and take slave cylinder off and then refit slave cylinder will o ring be o k or will you have to renew it again.

another photo off clutch slave cylinder when new when id took it out off box
Expert:  Robert replied 5 months ago.

Ok..firstly you dont need that much grease on the input shaft..just a light smearing is fine..but thats too much you've put there..... also as far as the pictures go with the slave cylinder you seem to have it all in order..but i notice you may have 2 or 3 spring clips missing..like at the flexi pipe joint and the join at the slave to bleeder..make sure you have them installed..dont see the bolt pic but just one and half or twice round the bolt should be fine with the white tape.dont put alot..

Customer: replied 5 months ago.
The only spring clip that i thinks missing is the one that clips to the flexi pipe joint that joins to the slave to bleeder If you think i need any more clips fitting tell me which ones.
Customer: replied 5 months ago.
The new clutch slave cylinder seems to be o k for gearbox. As you see in photographs the new one is silver metal where it joins to gearbox and old ones black plastic where it joins to gearbox. Do you think the new clutch slave cylinder is o k for the gearbox.

Wanting to put cylinder head back together now wanting to know if i need check anything on valve followers as there is a hydraulic tappet in the follower as shown in photograph. The engine had done 170000 miles and hasnt been run since 2013. Are all the followers the same does it matter if you put a different follower on a different valve spring. Do i put a small layer of oil on valve spring washer.
Expert:  Robert replied 5 months ago.

Ideally you want to match the buckets/valve springs/valve to the way they came off..if in situation they are mixed up then it should be ok to fit as you describe..you will need to bleed them..you should be able to find videos on how to do that on Youtube etc.
