Put the rocker assemblies back on my heads and drove home to san diego.
got very loud rocker noises coming from the engine
re adjust the valves.
drive it for a little while and bigger clacking noise and starting to lose power.
I think i *effed* it up installing the new studs and then torqing the rocker assembly nuts with my old torque wrench. thought i seated the studs properly, and torqued the nuts right, but now the valves dont seem to be holding an adjust.
so what the worst that could have happened?
stripped the studs from the heads right?
Time to pull of the rocker assemblies and really get a view of what's going on.
any way to tell if the stud is starting to pull out without cranking on it?
Yes, look at how much is sticking out past the nut. They all should be the sma elenght and they should not be that long. I feel for ya man. This was the last problem that I had with my 2.0. If you used the old holes they might be stripped and you will need to get special larger studs and have them threaded in.
they were the original holes.
I'm thinking the loud valve noise that prompted the tinkering may have been a prelude to my current problem.
Every time i adjusted them they would be quiet for a few days then get noisy again.
No worries though. I was thinking of pulling the motor to figure out the geometry and do some rust repair anyway, this will just be another rung on the ladder.
Damn it was running good too.
i'm going to have a beer.

I've only adjusted the valves once since i got the car.
Put maybe 2000 miles on it, and always thought it was a little clacky on the passenger side.
Even had another person at the WCC comment that it sounded like it needed a valve adjust. I pulled one of the adjusters and it was pitted badly, hence the new adjusters and rockers.
Only now its loud on both sides. Really loud valve noise.
Flat cam. jEEEESH.
Sure Hope not.
I just spent 50 buck on oil and filters.
will know more this weekend.
thanks for all the feedback.

Hey Bear, once you get the engine out, you could bring the heads. stuff over here.
I've got my own valve and seat grinder to rebuild heads, also sand blaster, reamers, lathe, milling machine, etc. Still a tool junky. Been building heads, engines, for a long time. Of course, most of the engines have been in the multi-ton, massive horsepower range. But I've always done my own heads since I got the valve grinder set up years ago.
The only problem I have about working on other peoples cars, is I don't have room/parking for them.
Give me a call, or pm me if your interested.
Regards, Don
went out and turned her over to listen again.
the loud clicking noise is not as apparent when its cold.
there is oil smoke exiting from the passenger side exhuast pipes.
pulled the plug wires one at a time, cyl #1 makes no effect to idle speed.
generally rough idle.

So here's a picture of the problem.
I took the valve covers off, and the #1 rocker assembly was completely loose meaning the valves were not opening on it. I pulled the nuts off and the rocker assembly out, and when counting the pieces noticed i was one washer short. I found it down in the pushrod tube near the lifter and extracted it with a magnet tool.
these little bass turds came from my FLAPS and worried me when i bought them. The guy said they were fine and i believed him. Cheap compared to the hardened german ones i'm used to, and it broke of course.
Any predictions?
a little oil smoke never hurt right?

Sorry, for the scare, it's not a flat cam, it's something simple. |
it aint fixed yet!
I need to find some proper german wavy washers and get it back together to see if she still runs alright. I'm more than a little worried.
Then plans to pull the motor and check/set up the geometry, powder coat the engine tin and paint the engine bay if i dont end up needing to rebuild the heads.
If this motor goes south i'm going subaru
I have the new German wavy washers in stock..... If you can't find them locally..
Don't give up on the aircooled power......
ok, i'm not giving up yet.
NEVER give up...
If you want something with a Subaru engine- Buy a damn WRX!
i still have this to play with.
I'm talking about the car.

60 was a good year...
Its needs a MassIVe 4...
Okay swp to a suby in the 914 and keep the bug for a heart transplant from the teener..
I was thinking of rebuilding the original 36hp.
Want about a massive 36hp?
so i put the new rocker assembly's on with .030 spacers.
cyl #2 and #3 still are too close to adjust. Is there something about the rockers on those cylinders that makes them closer? I can see that those two are the same type.
I need custom pushrods.
BTW- it lives! going for a little drive. no apparent problems.
still in need of custom pushrods i think.
I love beetles.....it would be so cool to have one.
there is a '68 for sale....the person wants $4000 for it. rebuilt engine. type1
all i have to say now is.
