Ok, This has got me thinking now that things for my A2 TDI swap have started coming together.

Should I just get a "Good used" engine and drop it in or rebuild a core? The last engine I rebuilt myself without experienced help was a 2 cylinder Briggs and Stratton :-P.

It would be easier and quicker to just drop in and go but, I'd hate to put in the engine only to have a problem 10K down the road.

Roughly what does a 1Z / AHU DIY rebuild run? I'd give it a shot, I have a Bentley  :wink:


when i got the motor, the intake was gummed up pretty badly from the EGR system.  I want this car to last through some tough winters so I've decided to do it right the first time.  so the head is being cleaned, check for straightness.. see if I need new valve guides and whatever.

the rings will be costing me about $230 or so total, but well worth it since they are going to be total sealed.

for the bottom end you can probably get away with polishing the crank, and new bearings.  

the motor have is from europe and looks good... also the x-hatch in the cylinders is still there, and there seems to be no ovaling of the cylinders, and they look nice and tight.  the motor has around 130'000km.

i could have just installed the motor as is, but the gunk in the intake didn't look too good.. i was affraid of a piece of it falling into my cylinder and doing some bad damage... plus there's probably 5-10 hp worth of power just by cleaning that crap out!!!  :lol:

Guess you should find a friend just over the border who can order stuff for you. Then you just need to "visit" him. No, really, I had those parts on the way down. I was just showing them to my friend.

come to think of it, i probably could have bought a custom ring set from them to fit my application, with one of their diamond coated style rings.

i'm sure their rings are as good as goetz, but this is the route i've taken, and i'm sticking with it.  so far hillfolk'r has had very good results!

edit: actually it seems they only have 79.00mm bore rings & 80.00mm bore rings... looks like i would need to oversize to buy their stock rings...  much cheaper buying goetz, than pistons and rings...

well project is moving quite slowly... bottom end is all done.

im looking at the autopartsonlinecanada site and it is showing me two different sizes.  7mm and 8mm valve stem seals, and also showing me the option of buying Viton valve stem seals.  is there any benefit to viton valve stem seals???  they only list an 8mm viton seal for the 1Z engine (my engine code is 1Z)

can anyone help me out? i'm guessing that i need 7mm as i'm not oversizing the valves.  if the viton valve stem seals are superior, where can i buy a set of 7mm???

thanks!

Most of the 1Z's had 8mm valve stems. You could probably measure to be sure.

ok i'll check.  do you know anything of viton seals?  i'd imagine them to be superior, but not sure.

thanks

yep... over $200 :(  but to me that's worth it.

i found my goetze rings on
mr or m-r or m-r-autoparts.com
(sorry on screwey address)
for around 20-25 a hole!!!!,then the 125 from total seal,yea about 200$
trust me they are worth it
my breather hose exits in the drivers wheelwell over the control arm
theres NO drool everywhere from nasty blowby
no smoke bellowing out,if anything  you put your hand in front of the breather hose,it pulses  air back+forth
thats just the pistons moving up+down in the crankcase  displacing air basically ..
oh my rings cost a little more,cause i had them  modify a 5th set,in case i broke one on installation
they told me that they were so impressed with the (worn out) stock ring set i sent to them for examination,that they honestly didnt make rings that nice
and they would like to attempt  modding a stock(new) set
since the chrome plating didnt chip off the ring when machined(that was their concern),its a good mod to do
my ahu had 8mm valve stems
id stay away from aftermarket valve seals
ive never really seen any problems with valve guide seals on the vws(yea years +years ago),just make sure your valve guide clearance isnt excessive
Throttle cables ftw

It's been a while since I've posted anything about my m-TDI build.  So far what I have had done:

Block:
- light hone
- new bearings installed
- intermediate bearings installed
- pistons cleaned and installed with total seal rings
- block hot tanked

Head:
- new valve guides
- new valve stem seals
- new gaskets etc
- very light planing just to remove some surface crud built up.
- hot tanked to remove all the EGR crap

To be done:

- clean block for paint (i wish i sand blasted it!!!)
- install new gaskets
- get new oil pan then drill & tap it for a fitting for the bypass filter return
- get turbo fitted up and connect mechanical VNT linkages.
- Install all accessories such as a/c, and alternator.  still contemplating converting to mechanical steering, or just plain running it without power steering.
- figure out the wiring such as temp senders, and glow plug coolant heater setup (probably have something hooked up to the glow plug sensor that shuts them off when the car is up to temp from a re-start)

Now for some pics, because I know everyone here loves pics!







Notice on the #2 cyl that I have circled a questionable mark?  looks to me like a nice hairline crack running down a coolant jacket... I'm going to hook everything up and hope for the best on that one.  I really hope it isn't anything serious  :cry:



Yea its a little painstaking to get rid of the paint on the block.  IMO it will be worth it.  I'll be painting it something nice and bright (maybe even white) so I can detect any sort of leaks, etc.





I wish I could find the pic that I took before of what it looked like; all sooted up.. it wasn't nearly as bad as the manifold I got, but still a night and day comparison.  Worth 5 hp?? 1-3 mpg?  :lol:

I definitely have the block checked by a machine shop to verify if the #2 hole is cracked.  It's easy to check now rather than going to all the trouble and finding out it's bad and more than likely ruining the piston.
