leave it alone or you may break it. It may not want to come out. If you want something to work on in the lubrication system, and I would have left the mount alone, get one of these and cut your filter open. Also if you pull the strainer plate off, 9 ft lbs when you tighten the nut or kiss the engine goodbye.

Thanks for confirmation. This is why I was gentle, only using a rubber mallet for some taps and a few screw drivers trying to pry off. And the strainer plate, that is another thing I am leaving alone for now. The consensus seem to be it is not worth the hassle. If it leaks I will deal with it then. On to the next steps. _________________ -----------------------------------------

Got the 3&4 head off today. The 2 outer top studs came out but I got them threaded back with some high temp thread locker. Look similar to the other head.
Lot of cleaning of the lower case.

Today I cleaned up the threads on my spark plug holes. Tool worked great on 3 holes but the lucky cylinder #3 has no hope. I will need to install a saver in this hole. Any recommendations?

I would find a local AUTOMOTIVE MACHINE SHOP, not a mechanic, and have them do the work using a drill press and table. There are a couple ways to repair it. A time cert can be used, or it can be tigged, milled, re-drilled, and tapped. Time certs sometimes come out, helicoils in that situation may leak. Be sure to look carefully at the roofs of the ports, and between valves, to make sure the head does not have cracks in it, or you are wasting your money fixing just the plug hole. Also inspect the valve seats carefully because they have a tendency to fall out when they get high miles on them.
Since the whole engine is not going to be rebuilt, it doesn't warrant a lot of money but if you can't find someone local, you might consider sending both heads to Brothers VW Machine Shop in Ontario California, and have them go over them and do any work that needs to be done. That is what I probably would do in this situation. https://www.facebook.com/pages/Brothers-VW-Machine-Shop/158542860835505 _________________ George Carlin:

I am fully convinced now that I need to have these heads inspected and rebuilt. It would be a disaster to drop a valve. The spark plug hole only has 2 threads and is the final straw on this camel. The exhaust studs need to be replaced and the engine tin holes re-tapped on 1 head. There are no VW specialty machine shop anywhere near me. Vintage VW is just not very popular in Texas.
I got email quote for $700 for both to rebuild.
Also, any thoughts on the heads sold by Bus depot? They say new AMC. That would be cheaper than rebuild but I have a feeling you get what you pay for.

Thanks, I did not know that search for shops existed. I see some parts shops and repair shops in Houston area so I will certainly check them out. I would still need to ship the heads to Dallas area, nearly 5 hours away. _________________ -----------------------------------------

You want a bonifide machine shop to do the work. Don't send it to another mechanic who will pull his drill and thread restoration kit out, then hand lap the valves. You need someone who will refurbish the head so you can get another 40,000 - 50,000 miles or more out of it. _________________ George Carlin:

I have decided to ship my heads to Brothers VW. I did get estimate from the Automotive Machine in Dallas but they recommended new AMC heads because their estimated would be very high. I realized those Bus Depot are the same recommended AMC heads, which would be over $1200 with shipping.
Brothers VW has good reviews here on Samba. Now that I am going down this path, while I am all the way deep in this motor, I will remove the jugs and do a better inspection and cleaning of pistons. I did use the thinnest feeler gauge around the edge of the rings and I could not go around them. Not sure if that is a big indicator. In for a penny, in for a pound I guess. I have the Tom Wilson book for reference now.
I guess what I don't know is what is the pros/cons of just doing heads now, and jugs/pistons/rings later, or do all at the same time. I guess the labor in tear down.
I have done a lot of cleaning and will be repainting tins. etc... _________________ -----------------------------------------

If you pull the cylinders off and you will have to hone the cylinders, and replace the rings. You know that, right? You cannot get dirt inside the engine so be extra careful moving forward. _________________ George Carlin:

I did not know that. I think I will leave alone now. I will be test firing on bench and will test compression again before I re-install. _________________ -----------------------------------------

Show me good photos of the tops of the pistons. If they are even black all around then it is not burning oil. If there are big spots where the carbon is washed away, then that means the rings are leaking and the detergents in the oil are washing away the carbon.
Ask Brothers if they resurface lifters. If they do you may want to consider it. If you take them out they HAVE to go back in the same bores unless you have resurfaced them. If they are resurfaced, break the cam in like a new cam and use the special cam lobe lube to break them in.
GM makes a top cylinder cleaner that is really nasty stuff but it softens carbon. You can paint it on with an old brush and wear gloves. Then wipe it down in a few hours. I have let it sit overnight. Just don't get it inside the engine where it can attack seals. Use it just to soften the carbon. Ebay is the only place you will find it and the prices will vary from $30 to $80 a can. WD40 with a 3M rotary brush will work but they are pricy too. I would not use a wire wheel.

I will take some pictures tomorrow but they are consistent black. How do you remove the lifters? Is it just a strong magnet?
What about this nylon wheels to clean carbon ?

for $11 I'd try it. Just use some WD40 on it. It is mostly solvent.
Yes, a magnet pulls them out or snap ring (duck bill) pliers can grab them. Make sure Brothers does them before you pull them out. If they don't there is no reason to remove them. You won't like what you see when you look at the camshaft anyway. It will look like this most likely. If you roll the engine on its side they may fall out, and then you will not know where they came from. They must go back in the same bore unless they are resurfaced.
The lifters have a convex surface. As they wear, the center wears and they get flat. Where the two lifter edges overlap, they wear the center of the lobe. Each lifter actually rides on the outside and not the center because two lifters share a lobe. Meaning that this cam below may not look pretty but it could be used for a while more. To replace it means a complete engine rebuild, which I think is a lot more than you need or want to do. Get comfortable with the engine first and when the time comes, you will already be prepared to work on it deeper.

I wanted to inspect so I managed to get 1 lifter out with a magnet. It has a flat top and very slightly mushroomed top. I assumed the other 3 on that side would not come out due to the mushrooming. I sprayed some fogging oil in (i didn't have any WD40), maybe it will help. I will give it another try and try the other side later today.
I will share pictures later and I will use my endoscope to examine the lobs. _________________ -----------------------------------------

what do you mean by mushroomed? I know what the word means but not in the context of what you are seeing. The lifter should be curved with the center higher than the edges. As it wears out, the center wears away and it becomes flat. Then the edges start to wear the cam lobe in the center because that is where opposite lifters overlap on the lobes. When the center is still higher, the edges do not touch the cam lobe.
I snagged this off crankshaftcoalition images to show what it means to have a convex crown. When the crown wears away, the edges of the lifter wear into the cam lobe. Since two lifters are shared the same lobe on a T4, where they overlap the cam wears faster, and that creates the wear pattern. Resurfacing puts the crown back in, but since the steel is hardened, it can't be done if the lifter is too worn out, but in that case the cam will normally be at the end of its life too. It can be reground also, but the hardening is gone so it wears a lot faster if too much material is taken off when the cam grinder, regrinds it.

Mushrooming typically means the metal is too soft. There would also be no way to get the lifters out without splitting the case. |

Sometimes there is a buildup of baked oil on the end of the lifter that makes it difficult to get out with a magnet. _________________ Mark
