There are just too many to list....
The SRT 4 was with very little mods a 12 second car
Yep, you can say the same for a GTI, but the Neon was also a back-of-the-lot rental turd that after 75k miles felt like it was going to fly apart. A GTI with a quarter million miles on the clock still feels solid and well put together, even if its on its third engine by then, LOL. (I don't think I've ever seen any Neon on the road for that long).

I have a hose permanently connected to my intake. When my intake was like that it actually jammed up my anti-shudder valve and I barely got home one day. I ran half gallon of good degreaser through the hose turbo and intercooler all to the intake while running, and then another half a gallon of diluted degreaser in water, very slowly over about 60 miles. My intake passages so clear you could eat off of it. Well except for the oil that keeps accumulating, I really need a oil catch can
Volkswagen was actually researching this back when these cars were still new and in warranty. Resulted in a few bent valves and blown turbos. They eventually dropped the cleaning by chemical/fluids and returned to manual removal and cleaning for warranty purposes.

Whether you do aerosol cans, chemicals, for a fine mist of water, to the turbo it's all the same, drop that's hitting the impeller spinning at a high rate of speed, so it must be done as little RPM as you can manage say after you're going downhill and coasting. But you need enough engineer pm so the water doesn't just settle in the intercooler, about 2,000 RPM. High speed, downshift, coast for 10 seconds and give it a few pumps of water.

I once had a car I really didn't care for, but it all sorts of issues and to clean the Catholic converter for emission testing I warmed it up and let it have the garden hose had a fairly steady mist, more like spray, with a bit of throttle it could drink about a liter of water without the engine even cutting out. Clearly you don't want to turn the garden hose on full, and the fine mist you just want enough be very slowly decrease the oil is to residue so it can go where it was supposed to go anyways

No doubt, it's just that it was a quick car for being a factory car that nobody really noticed

Why would you want smaller instead of larger? It's the soft rubber that adds more to rotational mass than anything
I love 14 inch wheels with big gushy sidewalls, and narrower tread widths being available nets you way better winter traction
too bad they're turbo-rare on the junk pile any more

had a pair of 27" BFGs that I was gonna put on with the aforementioned caravan wheels but they ended up on a lawn tractor when they wouldn't fit

Well not today but the other day changed the t4 rotella/engine restore treatment for like 3 quarts of mobil delvac and 2 quarts of quacker state full synth 5w30 due the shear film strength as extolled at the 540 rat oil page. Runs silky smooth and is actually quieter, the t4/engine restore only had 1k miles on it. Odd quacker state doesn't seem to be in the diesel oil biz so I put them there.
Hopefully the link isn't some site forbidden at tdiclub.

Biy that's a lot of reading. Can you give us the short-short version?


If you guys like the oils, read motoman engine break-in procedure. Controversial, but makes tons of sense

You could also disconnect the windshield washer nozzle and run it into the intake. Put the engine on the limiter and pull the trigger on the water. Or if thats a bit to squeamish 3k rpm is fine. Redneck water injection.

Luckily cardenas made an account at 1:49AM today to tell me "Good day Mate, you can check with Bonnie Burnett. she has it available, her late husband was a member of this forum you can text her at, (618) 842-8832. And she's parting way with those items." in a private chat about wanting a vacuum pump o-ring. :rolleyes: Reported as a scammer.

Do you happen to know what vehicles came with 14" 5×10̷0̷ with 57.1 CB? I want 14s. Also what size tire do you use?

Not really controversial, anyone that's done any amount of dyno break in, can confirm the rings need dynamic load to break in properly. You can literally watch it on the dyno display. Picks up power, less blow by, better response.

Last weekend got a lot done. Drove up to Nuje's on Saturday and got the timing belt done. Learned a lot about the job... while I certainly understand it better, I'm still reluctant to do it myself. The only engine I've done timing belts on was my E30 Eta engine. WAY LESS complicated, no special tools needed. But very glad to have it done. Thank you Nuje!(y)

Sunday was oil change, fuel and air filter day. For some reason my fluid extractor was being dumb... I got about half the oil out. I even tipped it up a bit. Ended up having to pull the belly pan. :rolleyes: Finished changing out the vacuum lines I started the day before and the lines from the injection pump to the injectors. Everything running well. Had to get back under yesterday... I didn't get the upper connection of the pancake pipe back in properly on Saturday and it popped out, giving me EGR and no boost codes. As soon as I got under and starting looking at the turbo vane, I saw the pipe. Got the little ears in properly and locked down. All good. (y)

I just came across two different Beatles locally, both gas though, both very interesting for winter vehicle purposes so my nice TDI would stay nice instead of get salted

The short ver is he doesn't make it easy for us by making a nice graph of the highest to lowest shear strength of a given oil. That'd be nice, one for gas engines, diesels, and atf. Just search for the oil of choice and read the shear strength
There are a lot of forii saying he's a shill for not revealing his secret test rig but I don't care, I've read enough of his blog to consider him legit street cred on the subject, at least way more legit than I am.

Here's his criteria;
"The Wear Protection reference categories are:
* Over 150,000 psi = SPECTACULAR wear protection
* 135,000 psi to 150,000 psi = AMAZING wear protection
* 120,000 psi to 135,000 psi = FANTASTIC wear protection
* 105,000 to 120,000 psi = INCREDIBLE wear protection
* 90,000 to 105,000 psi = OUTSTANDING wear protection
* 75,000 to 90,000 psi = GOOD wear protection
* 60,000 to 75,000 psi = MODERATE wear protection
* 50,000 to 60,000 psi = UNDESIRABLE LOW wear protection
* Below 50,000 psi = CAUTION – EXTREMELY LOW wear protection
The HIGHER the psi value, the BETTER the Wear Protection.
Test result differences between oils of less than 10% are not significant, and oils within that range can be considered approximately equivalent."

For the 2 quarts of gas engine oil I used here's the important bits;
1. 5W30 Quaker State “Full Synthetic” (abbreviated QSFS), dexos 1 Gen “2”, ILSAC GF-6A, API SP = 152,674 psi
$5.72 quart wallyworld

In comparison this is the oil I used for the engine restore treatment as otherwise a synthetic oil might not allow the treatment to adhere to metal as well if at all;
240. 15W40 “NEW” SHELL ROTELLA T Diesel Oil conventional, API CJ-4, CI-4 Plus, CH-4, CF-4,CF/SM = 72,022 psi

And the synthetic mobil diesel oil comprising 3 quarts of the change after the 1k mile treatment;
234. 15W40 MOBIL DELVAC 1300 SUPER Diesel Oil conventional, API CJ-4, CI-4 Plus, CI-4, CH-4/SM, SL = 73,300 psi
(I used mobil 1 delvac extreme not the delvac 1300 stuff), $22 gallon wallyworld

Note the non synthetic diesel oil I used is hardly any worse testing than the synthetic I used! That was saddening to me as I, like a lot of other deludes, think synthetics are a true gift from the tech priests (Warhammer 40k reference) and the ne plus ultra (ancient latin for "this is the ****, yo") of lubrication! I figured use the best motor oil I could find at any given walmart (lol), gas or diesel, and add at least some diesel oil to any gas oil as the diesel oil will have the detergents and surfactants and dispersants and astringents technobabble or whatever to counter the soot that the gas oils are not crafted for. I created a homogeneous mixture ratio of 2 gas to 3 diesel quarts. Next time will prolly do 4 gas to 1 diesel. Put in a Mann filter, they seem nicely constructed. All I know is the engine seems to be literally quieter than ever as far as the usual diesel rattle at idle. Is the concoction any better than anything else? Who knows!
