CT Engine Restoration

[Grun]

Although I do not have the torque figures for the CT, I suspect 'Camperfan' may be confusing the flywheel bolt torque (253 lbs/ft in my book for the earlier Aircooled engines) with t'other end of the crankshaft.
Bolt is right hand thread.(i.e anticlockwise to remove) IIRC
Half inch (or threequarter inch) drive socket, long bar, lots of effort and wack it, is my recommend. Penetrating oil/Heat?

Cheers guys, took to a tyre shop who struggled to get it off with a pneumatic impact wrench. Cleaned it up soaked in wd40 and tried again it came off

It's the same torque for either end of the crankshaft! Think VW wanted to make sure nothing came undone!

Ok, my first tip: before splitting the case check for nuts still on. Check again, then check again.

Camshaft looks like it needs replacing, not the same as a beetle due to the hydraulic lifters. So i need to find someone to resurface as cant find a new one anywhere.

Feel free to comment.

The bearing is showing plenty of brass and will get replaced. These are beetle bearings so ive been told.

Those heads look ok but I don't think they were torqued down enough as there has been exhaust gasses leaking out over the barrell. This would have caused a misfire in that cylinder and possibly a knocking sound which tends to disappear as the engine warms up a bit due to the cylinder head slapping up and down a bit. (I know this as it happened to me... Bliidy copperease grease makes everything come back undone again!)
Get new piston rings... Pistons look fine although I think the heads and pistons may have been renewed at some time as those pistons aren't bog standard (mine are like yours) and the heads look fairly new too.
That camshaft... It doesn't look too bad... See if it is scored or worn. If it is get yourself another one (if you can!). If not, it could well be used again.
Keep your hydraylic valve lifters but strip them down and clean them, well worth it. I did mine a few years back and not once have they made the slightest noise when starting, even when left for days!
Doing a good job by the way!

Thanks for the info camperfan, its great news that you think that camshaft me be reusable and the misfiring explains alot! Going over to the north Cyprus tommorrow to visit a machine shop, hopefully they can sort some of the wear..

Are these a good price for Hydraulic tappets?

[VWCamperfan]

Yeah, that price seems ok but there probably isn't a lot wrong with yours.
If you do decide to strip them down, when reassembling they have to be kept under oil... A bit of a pain when trying to reassemble but all good dirty fun!

Don't forget there is the option to loose the hydraulic tappets and put solids in... if you do this then you can use a beetle cam too ( OK so the power range might not be as VW designed for that engine but lets face it will putting a beetle cam in a CT engine make it either better or worse?... I'd say not really!)

Watch that you DONT TRAP THE BEARINGS when putting the cases together - the bearing seats have studs that locate the bearings - EVERYONE makes this mistake at least once when rebuilding these engines

Damn ive just ordered the new lifters putting in beetle camshaft sounds like a good idea as it would leave mainly the case as obselete. Anyone know the cheapest place to get the bearings? how do i know if they are already oversized?

[toomanytoys]

"cheapest" isnt always best.......

The pic of the cam is very fuzzy so cant tell whats going on there... but any pitting or scoring will eat the new lifters in a "thrice".... what do the surfaces of the old lifters look like???

The CT cam does give very good low end power, for a 1600... if it can be polished it would be worth it.. I wouldnt run the cam on new lifters without a good polish though...

i just read this thread, thanks for the pictures, great thread!
