Official Mexican / Brazilian Beetles - All years

Another thing. I do not remember hearing about oil bath filters for mexibeetles. Did you adapt one? That'd be interesting to see.

Here's a link to one of the videos.

Hope it helps

PS: That valve is indeed expensive (here in Chile too).

Hopkin, do not use synthetic oil your 1600i engine, In Mexico VW recommends mineral oil 15W-40.
I use 15W-50 due the high milage on my 1994 Sedan (175,000 kms)

doesn't need to go up to the filter to be sucked into the idle valve, the tilt in the filter housing actually does that.
I second Antonio's oil advice, with a detail, IMHO: I use castrol 15W40 which is semi-synt after trying various full dino oils that alway left the valves clatter, I found with the semi-synt you can have good fluidity at start-up without the oil getting too thin.
hopkin is however in a much colder climate...

I saw the synthetic oil recommendation on the 1600i.de manual (BtlMexTechnica...), and that sounds reasonable for a brand new car, or a rebuilt engine.
How many KMs have you put on it since you got it? What about the previous owners? How long has it been since the engine was opened for the last time?

The mexibeetle my friend is fixing is from '98, it appears it had not been serviced since 2000, (and it seems it is 92.000 original kms). This has led to compression leaks, (which include overheat, clogged ACV, worn intake manifold rubber hoses due to heat and oil), amongst other bad stuff (totally worn clutch, for example).
As these motors age, a good rebuild when properly done can make wonders.
That's why I'd like to know how long has it been running, and the service it has been taken through during its life.

The car now has 132,000 km on it. It had 75,000 on it when I bought it in 2012.

It was stored in the UK for a couple of years before I bought it, with low (to zero) mileage each year. According to the records that were supplied with the car it had 48,000 km in 2002, and 70,000 in 2006, so only 5,000 put on between 2006 and 2012.

The engine has never been rebuilt, and was only out of the car once, in 2015. I took the engine out for easier access to the clutch return spring, I also put a new clutch in since I had the opportunity, but it really didn't need to be changed.

I change the oil at least twice a year, in the spring and fall, never more than 5,000 km between changes. Usually the spring change is after 1,000-3,000 km and the fall change 3,000-5,000 km. (This is due to our seasons, I store the car from Nov-Mar due to the winter and heavy salting of the roads. I run the car in the driveway at least once a month, if it is mild (~0C). Temperatures here range from -35C in the winter to +35C in the summer.)

This year, I did a mid-summer oil change, now ~5,000 km ago, so I'll do a third oil change sometime in the next couple of weeks.

Since I have lots of synthetic oil on hand, I'll use that one more time and then put in some 'dino' oil in the spring.

Personally, I'd clean the idle stabilization valve and forget about the dino vs. synt issue. IIRC you noticed the leak in winter, anyway...

Cleaning the valve (and the whole body) should help. The valve is all right.
About the filter... that’s the same we have here, just with a paper filter instead of a washable one. K&N is the brand of the filter element.
I’d run a compression test just to be sure.

Speaking of high mileage engines...
Long post

The bug on the shop arrived because of 'idle issues'. The owner hoped to find a simple issue, sensor related. (So did I). First red flag was the engine temperature: 116ºC, and oil vapor coming out of the filler neck.

The bug, and some others in progress (1 brazillian, 1 1303, 1 mexi cheaply turned to carburetors "For high performace" that was badly done)

A computer scan showed issues with some sensors which had to be troubleshooted, but none suggested the real problem: a vacumm leak so big that the ACV had to be blocked to pevent the engine from revving to its death.
As it was all dirty, the engine had to come out to see if there was any other damage on it.

The engine was insulated at this point...

The tranny was also covered in cooked oil. The bearing was rusted (original).

And there's more:
Engine mounts long gone (original ones), some nuts missing. Luckily, the front mount was fine, it is the original.

The clutch... There was nothing left there! It was also the original mexican clutch.

A good cleanup and a new bearing.

All the tins and other parts are getting a full cleanup.

This is the dirt buildup inside the accelerator body, due to the oil entering from the air filter through the ACV, dirt, and who knows what else.

Also cleaned... with gasoline.

New rubber pieces waiting

Now, the odometer shows 92.000 km. We found yellow paint on all the nuts on the engine, and almost everywhere else. (Never opened, never taken out of the car, probably, in 21 years).
My friend suspects this bug actually has just 92.000 km. It just seems it never got a proper service done (except oil changes), even though it has been resprayed.
The engine is leaking compression everywhere, but will not be rebuilt (the original budget was about 100 bucks, it is already over 500...

What do you think about it, could it really be under 100.000 km?

When I swapped out my clutch (in 2015) my car was at about 98,000 km. My clutch was barely worn, I'm surprised at the wear on (your) car's clutch at 92,000 kms.

Based on the clutch wear, I'm thinking your car, may have 192,000 km, or has been driven very hard for 92,000.

Hi, everybody!
The last warm days in Moscow we have met classic Volkswagens, it was pleasant to see acquaintances and to communicate with guys.
Ahead repair work in a garage for replacement of china quality of ball joints and front bearings.

that's a bit too heavy for an hyraulic lifter car. the lighter the better, esp. in a cold climate.

I'll personaly stick to 10w40. PO had 20w50 on it and the lifters were noisy 90% of the time.

In other aspects, can a faulty potentiometer (TPS) cause heavy fuel consumption? I verified mine and it wasn't changing resistance too much, I'm testing another old one (original) which is 'better', but still not 100% fine.
Temp sensors are working properly, air control valve works fine (cleaned)...
The gasoline smell on the exhaust is still present.

Your bug is not equipped with hydraulic tappets...
