Have been getting my 86 td jetta improved,
I found the exhaust manifold had loose nuts on the ends of the manifold. Suddenly the car started sounding like a tractor again. Put on some VDO gauges and now can verify the oil press, water temp and boost. Seems normal.
I took the top off the boost enricher on the pump and rotated the diaphragm about 180 deg. Now the boost comes up faster and the car accelerates better.
Need to put on a valve cover gasket.
Looks like this forum is on it's knees. Have always found good advice here.

Not too many people left running the little 1.6TD :-(

Use the one piece, reusable, rubber valve cover gasket for the gasser 2.0 ABA block.
-
Sounds good
A 2l gas with something called an aba block
Something to research
tks

Like this one fatmobile? Is this what you use?

They seem to want the 1.6 diesels to have the two part gasket on other sites.

Scrounger, it is the two-part nature and the lack of a good seal above the cam on the passengers' side that makes the stock one a pain. I like the one-piece for solving that bit of frustration.
-
I have had other vehicles with two part seals and usually that is where they give leakage.
So this part fits without problems?
I have some oil down the back side of the motor and the bolts seem to be snug. Figured that is the next motor item on my list.
I also want to see if there is a baffle under the cam cover as it seems to be some oil being sucked into the engine from the port that goes between the valve cover and intake boot.

Hard to tell if that is the right one.
It's a rubber one-piece,..
but some of them are stiff and some are all flexy.
I like the victor brand ones with metal support so they are stiff.
The ABA block was used in '93 to ??? Jetta 2.0 gassers.
Here are some more but I don't see any victor.
The elring might be stiff.

There are quite a few posts about this upgrade.
The stock studs have bald spots that keep the nuts from tightening down on the thinner valve cover.
The ABA cover is aluminum.
I replace them with set screws but some just add washers.

Thanks for the link, Fatmobile,
I did a search for an ELRING 915.653 and found a close up picture. Sure looks like it does have an aluminum plate. Thanks
An aluminum cam cover would be nice.

Another nice upgrade is fitting the biggest battery and a 2001 automatic tdi starter to the 1.6. Makes winter starting a breeze :)

Did not know that srgtlord.
The battery in my Jetta has been in it for over 11 years. Still has 12.6 resting voltage. It is an Optima with the cylindrical cells. It was in the car when I purchased it. Batteries just don't last that long, has me baffled.

The manufacture of batteries has changed. I have a couple from ~2012 that are still going strong, but anything made recently fails within two or three years.
