Hi again,

I finally took of the engine yesterday. I loosened the flywheel (it was super tight so I discard the loose flywheel theory) and noted the main bearing has no play and it's very shiny. To me it seems to have had some wear on that outer surface maybe to incorrect end play.

Also, my flywheel, pressure plate and disc have distinct marks on them. I'll post some pic when I reduce them since the iPad won't let me.

Thanks,

Hi,

I have been confronting a little clunk,on endplay at .005. I changed the bearings although the other ones were new, less than 800 miles. The case had no wear and the bearings weren't loose. You can feel a slight movement as you pull the flywheel.

Any thoughts?

i got recommended this for a performance engine

Andy,

I have an "old school / oldtimer" friend with a racing bug that sets his endplay that way. He recommended .007". The issue is I never had the clunk noise on it. Can the clunk be because I took off the helical style cam gear and now with the steel straight cut gears it has more play to it.

i got that advice from Richie Webb with the fast VW Cab :)

i'll have a feel of mine but pretty sure i get a clunk too, i thought it was from the flywheel end but could be wrong.....

what did you set the engine up at when building it?

Andy,

I ended up with .0055 on the dial indicator. It is not a CLUNK, CLUNK. Just a slight movement with sound. I believe this is due to the straight cut gears not restricting movement.

Good morning,

On Saturday I took the car out for a drive around 8pm with a cool night. We were on the highway and the car wouldn't boost and it felt a bit rough.NO POWER. The cruising speed was of 65 mph and the temps hit 325 on the CYL head temp gauge. I got to the place and let the car idle so it would cool down but the CYL head gauge didn't lower at all. This car would cruise at 270 / 280 before this teardown.

The car turns on quickly and without any struggle when cold or when it was that hot. You could feel the heat on it. I did not mess with my tune which I've run since 2015.

The engine was opened for a internal check and I changed the flywheel.

Thank you,

Did you change anything else beyond the flywheel?
Has it got plenty of oil pressure?
Is all the tinware in?
Are you leaning out?

Cos that head temp is a worry. :(

Hi Petew,

Did you change anything else beyond the flywheel? Yes, the main bearings.

Has it got plenty of oil pressure? Yes, idles at around 15 psi and runs at 40 psi I believe.

Is all the tinware in? Tins: Shroud, left and right cylinder tin, front plate, rear breast plate, pulley tin.

Are you leaning out? No,It's actually on the rich side cruising: 12.8-13.1. Before all this it cruised at 16-17 AFR.

One thought that came to mind last night: What if the cam / crank timing marks were off (:.)? Will it turn on? Overheat? I read a bit on this. I really don't want to open the engine again. The car turns on quickly without hesitation.

When I get home today I was going to mark with liquid paper the "V" between the crank dot marks and turn the engine until it reaches the tooth with the dot on it. If it marks the given tooth with the dot, timing is GOOD. This should work since you can see the crankgear through the gas pump mount and by taking out the alternator stand I can see the cam gear.
