Sorry im not mechanically minded, but im thinking of another cam to replace the one i alread have.

Where is it located? am i having to rip the old gurl to bits to get to it?

or is it a simple job?

help needed!!

ta!

Yeah you'll have to flip the engine upside down to change it otherwise the followers will fall into the sump.

Yeah, thats a long term project for me then! need help wid that.....

once engine is out and upside down, is it as simple as releasing the old cam, and placing the new cam in?

yeah it just slides in and out once the front cover and cam gear are off.

what cam do u plan on putting in with it?

comin from Freaks contact.

as he can remember

35/70

The best way to do this is to remove the engine from the car. Then mount it on an engine stand if you can as it will make things a whole lot easier.

Next, remove the rocker cover & carefully remove the whole rocker assembly, then remove the push rods. Keep them in order so that they go back into the same place if possible. Loosen the altenator & remove the fan belt. Remove the fan from the water pump too.
Remove the oil pump & the distributor. Remove the spark plugs too.
Drain the oil, all of it.

Rotate the engine untill it is upside down & remove the oil pan.
Remove the crank pulley, then remove the timing case.
Remove the timing chain tensioner, then the cam sprocket retaining bolt. Remove the cam sprocket & chain.
Remove the cam retainer & carefully, very bloody carefully, remove the cam. Support it at the rear so as to avoid damaging the cam bearings in the block.
Remove the tappets & check them for correct radius of their face. Either have them radius ground, or replace them with new. If reusing them, try to put them back in the same hole if possible

Heavily lube the new cam with a suitable cam break in lube, & insert it with even more care than the one you took out.
Re-assembly is basicly the reverse of the removal, but you will need new gaskets, & i sugest that a new timing case oil seal would be a good idea. Examine the sprockets closely, particularly the crankshaft one as it turns twice for every once of the cam one. There are fewer teeth in contact with the chain too, so this one wears more than the cam sprocket. If it is at all suspect, then replace the sprocket[s] & chain with new. Check the wear pad on the tensioner. If it is more than half worn, then think about a new one of these too.

Complete the re-assembly & adjust the tappets, & set the timing as per the book.
Hows the clutch? If it is old, then take it off & have a look at it. Renew if necessary. You would be pizzed if the old cluch started to slip with the new power of the engine.
Re-install the engine.

When you start it, run the revs straight up to the speed that is recomended by the cam grinder for the time that is recomended. This is a critical break-in time for the cam. Give the engine a complete tune up when it is hot & after the initial break in period

After the recomended interval, change the oil & filter, then enjoy the fruits of an afternoons work.
Like Freak said, it just slips in once the front cover & gear[?] are off.
Happy motoring.

Ok then!


not as simple as i once thought!

but a good project! but in the mean time may aswell rebuild her or at least alter a few more things! why waste the time of the motor being out?

plus my bottom end bearing has gone on me. i can continusoly hear a tapping sound!

If the tapping sound really is a bearing, then it's time to pull her out for a complete "freshening up", or replacement.
If you hone the bore,renew the rings & give it a top overhaul as part of the fix up, you will maximise the compression by removing the losses due to normal wear & tear in an older engine.
