Something to watch out for: loose turbo bolts!

[VWindahouse]

More suspense than an episode of C.S.I.

Love your work Jimmy!

I was going to threaten flashing his Audi back to standard but Jimmy fessed up earlier..

any updates on the solution that was being worked on by jmac??

[mikepologti]

by the looks , and by al means correct me on this one. jmac is maybe thinking of putting a pattent (or however you spell the damn thing) on his idea. no doubt hell release pics of the idea then.

I have taken delivery of my latest idea, just waiting for Vwindahouses Manifold to come back from the coater and ill bolt the turbo to his manifold with my new plates, just to let you know the pitch between all three bolts on the Polo Gti manifold are different so i had to get 3 made up at different lengths, I have enough made up to repair/resolve 6 vehicles. Im waiting with baited breath for the manifold to come back. Bolted up i willl know for sure, but let me tell you they look REALLY good. Time will tell and if they work itll be so much easier than the lockwiring Just lockwired a K04 and it was a task. Takes 1 hr per bolt to drill the hole for the safety wire. times that by 3 and engineers skill with the drill to save the drill bits. With Vwindahouses i will be applying the plates and the lockwiring for 2 lock safety ( aircraft stylee) as i have his already drilled just in case. Stay tuned for results, but as for pics unsure at this stage , because if it works well, its well worth a patent imo.

loose turbo bolts

having a full time business on the side ( www.captain thread.com) problem : turbo bolts are loose. i caught up with h100vw ( top bloke ) . who showed me the problem

1. redo the thread with a helicoil to make the thread tighter
2. ( i would recommend this one ) - convert the bolt to a stud and use spring washers and nuts.

By the way if anyone wants anything fixed ( see my website ) mention that your a member and we'll look after you.

This is my business , my staff are experts in threads / bolts. This is the cheapest and the best way of alleviating the problem.
( Option 2 )
If you live in Adelaide and you have the problem give us a call. Then post up the result and the thread will stop.

Sorry about the forcefullness but we've done this before and it's 100% successfull.

I had Jimmy do a 60k service for me and asked him to check the turbo bolts just in case. One of them is swinging in the breeze barely in!!!!! So back to the dealer who had to replace a window regulator and yet another strut top mount (2nd in 2.5 years). Assured turbo bolts were fixed and the invoice said it was done. The dealer also said I needed new rotors and pads - which i knew from Jimmy.

Almost said "Yeah like I'd let you guys rip me off and then do a crap job" but said I had that organised. So, today Jimmy does the brakes and cupra bushes and I ask him to check the work of the dealer (as you have to do). Guess what???

Turbo bolt UNTOUCHED!!!!!! Still happily loose as a goose!!!!!

Of course I'll be having a conversation with the dealer involved.

If ever proof was needed, NEVER let a dealer do anything to your car that doesn't involve warranty.

Even then, you need someone who actually knows what they are doing and really cares about their work (thanks Jimmy) to check it!!!! Incredible.

Oh, and I'll also have a chat about the nice little dent on top of the guard where one of their idiots dropped a tool...........

That's entirely consistent with my experience, and totally crap on the part of both the dealer and VWA. There's been enough reports to show this is a known problem...but they don't even know how or where to look.

Go up 'em Peter!!

Yeah it was a disheartening find really, i was hoping to see new bolts and gasket and a 2 second glance. Had a look and had the sinking feeling. poor show tbh.

Well, my Polo with 37000 k's started sounding a little noisy when first started. I thought little of it as I am very sensitive to noise. Yesterday I noticed when on full throttle beyond 4K it was making a raspy sound. Took it to my local mechanic, but could not replicate for him to hear. I left it with him to hear when its cold as blipping the throttle when cold was sounding worse quickly.

1 bolt gone all together, others loose (as was expected). Once again the info on this forum provided me with the info I needed to point my mechanic in the right direction straight up. Makes me feel all warm and fuzzy (and a smirk of hoping for more boost when its all back together).

Moral of the story, if your car starts sounding like a truck when you start it up, get the bolts checked.

Hoyhoy.

Noone the problem is keeping it together, especially when tracking.
Me has gone to extreme measures to try & overcome this, last track day was in Oct & the first track day that it held together since fitting the Ko4...

[jasn78]

Eddy, was reading a fast fours mag the other day and saw some bolts that have an expansion thing in the middle of them that when I saw these I thought immedietly about this thread, when I find the article again I will post the details.

You lads seen one of these?

K03/K04 Turbo Locking Flange - 034 MOTORSPORT

[Jmac]

i had some fancy locking tabs specially made up but didnt quite work in practice, shame, anyway yep seen these tabs but dont think its the loosening as such, lockwire as ive done on many aircraft applications ( however not with 1000 degrees heat is one of the best locking method) should be ok . Ive locked a couple of Polos and they have held up, however, its not always the case and i think its not the bolt loosening its expanding therefore it has to come loose. When fitted normally and expands , then with vibrations it will loosen especially when tracked as its getting vibrations from go to wo. No rhyme or reason folks, ive seen them loose on cars that dont get driven hard. The ones ive locked up have been good so thankful for that but not sure how to 100% combat this yet. We even tacked blobs on the bolts on the early Audis as they were accesible from the top unlike the Pog but man they still blew gaskets. Hmm. One of those things. I still reckon studs with nuts would work but access is the drama. I would love to try one with the engine out to see how it goes , That may happen someday. We have pointer invented in the UK which has been implemented here now for truck wheels for the phenomenon of loosening left wheels, this cant be fixed only watched by pointers, we might and hate to say it have to monitor this one
Cheers for now

I started noticing those pointers on truck wheels about a month ago, now I seem to see them everywhere. If it were more accessible we could be checking it ourselves or at least keeping an eye out.
