Vw 172 GTI

[Tommie]

Had another productive session on the GTI after work.
Installed the K-Jet, metering head, air box , injectors, warm up regulator, brake fluid reservoir, coil and a few other bits and pieces. The headlights were quickly fitted for a bit of a laugh.
Still got a lot of gunk in the fuel tank. Hard to explain, but it's got a tar like viscosity and the fuel smells stale.
Might have to look at another avenue as the lacquer thinners ain't doing much.
Any advance from someone that has dealt with something like this???

Hi Tommie,
She's looking great! ..See I told you it would come together quickly!

For the fuel tank there is a product out there called oven and grill cleaner, it is sold under different names by commercial cleaning suppliers (if you were in Sydney I could get you some, my parents sell it). It is basically a supercharged caustic degreaser, pour it in straight, and do the same as you are with the thinners, leave it a while shake etc. and it will eat anything oil-based away. Wash thoroughly with water until it doesn't feel soapy anymore and allow it to dry (or help it with some heat!). It should do the trick, Ive cleaned so many hardc to clean things off with it I've lost count! Just don't get it on you....IT BURNS!!!! .... I know, I found out the hard way!!!!
Cheers, Scotty.

Cheers Scotty,

Been flat out everyday working on the GTI. It's a matter of work, and then work on the car straight after work till late...
Had a win with gunky/ rusty fuel tank.
Bought some POR 15, automotive fuel tank repair kit. Probably the best $160 I've spend. The kit came with 4 litres Marine Clean, 1litre Metal Ready, 1 litre Tank Sealer, Patch cloth, Pouring spout and inspection mirror.
First I used the marine clean to break down all the gunk. Used some really hot water and it worked a treat.
Next the metal ready, which is basically a prep for the Tank sealer.
And lastly the Tank sealer.




The trick was to make sure the whole tank got covered. You have about 20 minutes for that as it starts to cure.
It takes about 3-5 days before you can pour fuel back into the tank.
So that's another job ticked from the list!

Next on the agenda Interior.
Big thanks to Dan ( Lucky 13) in assisting me with the interior.
Having no experience with roof linings and hearing all sorts of horror stories, the roof lining came out surprisingly nice. Definitely not my favourite part of the rebuild.





Still got to sort out the cut out for the sunroof.
We've also installed the fuel tank, interior carpets, front and rear seats.

Had another huge night last night and called it just before midnight. So bloody close now!!!
Got the motor turning over, started it up and done the timing.
No fuel, water or oil leaks
Took the photo earlier in the night, but front and rear bumpers are on too, as well as the Windows. Not long now.

Looking good Tommie, you really are burning the midnight oil!
The marine clean has the same active ingredient as the oven and grill cleaner, so it destroys anything oil based.
POR-15 is an awesome product, you wont regret using it, I once did the inside of a 5000l tank on a water truck with it, it saved them replacing the whole tank! Though it was much harder to roll around than a fuel tank

At the rate you're going,you'll be ready for another project soon!.........Or a holiday!!!

[roccodingo]

The cleaner is Sodium Hydroxide ( caustic soda) same isht used in the hot tank for engine blocks and other STEEL / IRON parts. Dont use it on alloy stuff ( disolves alloys )

Build is looking good !

[GeorgeMK1]

Man, you go 0-100 real quick.

This build has been quicker than most folks on here for years with their mk1's hehehe. Looking real good. Also the fuel kit is awesome, as are POR15 as a product in general.
Planning to go double, or quad lights?

[Tommie]

Hi gents thanks for the kind words and advice.
Probably going to go double lights George, to me they just make the car look wider and lower.

To all the Mk1 gurus.

I NEED HELP !!!!

So the car went for pre- roadworthy today. And it's not looking good.
The car starts and idle . The timing has been done too I might add.
When you stand on the loud pedal it revs freely to 6000 rpm, there are no hiccups or stutters .
As soon as you stick it in first gear and try to drive there's no power, the car doesn't die or anything, there's just no power. So as soon as it's under load it looses all it power. Had the Kjet fuel pressure gauge on it, and it reads 5bar. It's got enough fuel pressure.
Has anyone come across something like this? Or heard of something like this?
Save to say it will come home on a tow truck tomorrow and I'll have to go over everything.
Not happy.

Haha, I know exactly what you mean. I grew up in Jo'burg,and every weekend, there would be illegal drags going on, happening on Jules St, near Primrose. There were, and still are some VERY fast mk1's in SA, and it has the best illegal drags I've ever been to, to this day!!

Howzit gents can relate to the ill legal drags I also lived in jo burg....remember the golf an Lamborghini incident @ jet park drag good times
