kinda more of a feeler to see if theres such a thing as 1mm os pistons for a 1.5 engine. i need some so i can start building my 1.5TD with oil squirters. the pistons dont have to be notched. cause they never came that way for a 1.5. lemme know what ya got or know of?
-
Welcome to the club. Thats why I'm looking at 1.6TD pistons on 1.5 rods. Oversized 1.5 pistons are currently being cast from unobtainium.
There may be some NOS floating around out there. There was a set on the Samba that someone got to befor me.
Good luck
-
thanks for the heads up. if i find some, i will let you know where i find them. ive already got a set of 76.98 pistons in good shape, but i need to go to 77.48mm bore. my turbo block is already at 76.98 and its pretty well worn out.

That'd be me. They were standard size, however; is that what you need?
-
Nope. I'm planning on useing a TD block, so i have to bore at least to the first oversize. Glad I didn't get them.
They were advertised as 1MM oversize. :roll: Did you buy them because they were suposed to be oversized?
Jeez, I wonder if oversized pistons ever existed for the 1.5.
-
seems like using sleeves or modifying 1.6 pistons is the only option for those old blocks...
-
seems like sleeves are the way to go. anyone use prothe's sleeves? i really dont want to go the extra mile to do a job right and then find out that the sleeves were of ***ty quality. that would tend to upset someone :evil:
-
I'm going to be looking through a whole stack of Bentlies this weekend to see if there is a rod in some other VAG engine that will work with a 1.5 crank, and 1.6TD pistons in a 1.6TD block.
From a few cursory measurements, it looks like the shorter stroke of the 1.5 crank is made up in about 1/2 in the wrist pin height, and 1/2 in the rod length. I'd like to have it all in rod length and be able to use the 1.6TD pistons.
-
that would be really freakin sweet. i dont even know how long the stock 1.5 rods are in mm size. i wonder of some sort of gas rod might work? like a 1.7 rod or a G60 or something? it would be sweet to have a 1.5 TD motor.

I got this info from a friend of mine who's moved quite a number of various VW engines through his shop.
As for rods, ALL less-than-1.8L engines (and less-than-2.2L I5s) have 136mm rods. All 1.8L engines except the G60 have 144mm rods; G60 has 136. Audi 3A has 144. VW ABA and AEG have 159. All 2.2L I5s have 144mm, except for 10V turbo engines, all of which have 136mm. The Eurovan 10V is an oddball with a different rod that has an enormous wrist pin.
So that gives you rod lengths, at least, for the gasser engines.
Also, 1.7L and smaller displacement engines have rods with smaller big end bearing journal than the diesels did. The bigger engines' rods (144mm rods) are apparently compatibly sized with the diesels'.
-
im still not sure how long the 1.5 rods are. they are not the same as 1.6 rods or anything else for that matter.
-
I used 1.7 rod bearings;
for the 1.5 diesel crank/rods.
-
so a 1.7 has the same size bore as an AAZ correct? and what stroke does it have? its got the same length stroke as a 1.5 doesnt it?
-
Hopefully all rod dimensions are in the various Bently manuals. I'll have access to about 50 different Bentlies for VW and Audis this week end.
-
omg, are you going to what we would think is heaven? sure as hell sounds like it. haha :D
-
I am not sure yet,
but a good friend of mine may have access to a whole pile of NOS 1.5 pistons, std and oversized. (he bought an old distributor who is out of business)
He is good on parts (owns a VW parts store)
but not too intimately familiar with Diesels.
In his looking, he seemed to think that the pistons may have the same diameter as the 1.6 (76.xx) but be a different part number?
If you can provide me VW part nos, I can confirm whether he has them or not.
He thought (according to his research)
that he had piston and ring sets in std, 20 (?) and 30 (?) over....
Rod and main bearings as well. he has some "Metal-Leve" bearing sets, and some brazilian manufacture piston sets.
All stock is NOS from the 80's...
If you can let me know what you need, I can see if he has got them.
Thanks!

i dunno what the part number is, but you can get 76.48, 76.98, and 77.48 size pistons and rings for these. ive got a set of 76.98 pistons, so i know oversize 1.5 stuff exists.
-
well, you gotta help me help you.
He has a ton of stuff, including many diesel pistons.
He thinks he has oversized 1.5 pistons w/ rings, but needs help with the part nos.
Any gurus wanna chime in?
-Brad
-
ill see if my grnadpa still has his oversized piston box, it might still have part numbers, they were KS pistons.
-
seems like the aftermarket guys still use VW part nos,
hopefully we can cross them.
I saw this thread awhile ago,
and then my buddy mentioned that he had some old dusty diesel stuff
(dusty old boxes, that is, with brand new perfect parts)
and I thought I might be able to help here...
Let me know!

If anyone is interested.... I have a new set of German Mahle's in 1mm oversize for 1.5l. Pistons, pins, and clips. New in boxes- 3 sealed and 1 has been opened and looked at.
-
What's the part number?
-
I will chech the part # when I pick them up from the machine shop on Monday, but heres the story.... I had a 1.6 block bored 1mm over to match a new set Mahle 1mm over pistons that I was lucky enough to find at a local shop. I took the block and pitons to the machine shop and in the meantime ordered everything else for a fresh build. When my wrist pin bushings came in the mail I ran them right over to the machinest with the rods. Long story short, when he went to install pistons to rods and press and size new bushings he found 22mm piston pins instead of 24mm like 1.6 rods. So... the pistons I bought which were supposed to be for 1.6 diesel turned out to be for a 1.5 ///- blessing in disguise I guess!
Im not sure which way to go here but either way I have a 1.6 block bored and prepped 1mm over with a $275 bill pending and no pistons to match. I guess I will find another set of pistons and hope they mic out to spec and can use them in the finished block. The great thing is that German pistons are sooo precise that I may be OK, eh?
If anyone has any other solution I would sure love to hear it! Otherwise I will sell the 1.5 pistons. The machinest offered me $450 already- explaining he has many customers who just want to rebuild what they have and he hasnt come accross any oversize 1.5 pistons for 25 years, let alone a German Mahle set.
So much for keeping it short!

Back to the OP,
My friend has confirmed that he has 1.5 Pistons, New Old Stock.
He has them in in std bore, and the first two oversizes.
Brands vary, but mostly brazilian.
These come with ring sets.
He says $300 per set is what he needs to get,
if there is any interest, send me a PM.
Thanks,
Brad
-
but does he have them in 77.48 mm? i think over sizes go in half mm steps. 76.48 is stock bore
76.98 is first OS <-- where im at right now with my 1.5 and 1.6 TD
77.48 is last OS on a 1.5 engine, not sure about a 1.6 tho.
and if he has any, does he have any german sets? cause the only way im paying 300 bucks for pistons is if they are quality german parts. brazillian parts would probably still be fine, but i favor the german parts.
-
Sorry, update:
Yes, he has sets with rings in std bore, and .5mm and 1.0mm oversize.
I know the .5mm over are Brazilian Metal Leve's.
I can inquire about the 1.0 over.
All this stuff is from the 80s...good old stuff.
I was surprised when he told me he could move them at $300 and cover his expense.
That seemed cheap to me, as you can easily spend that on similar pistons for 1.6, but those are actually available. (I just spent $80 buying a set of rings for my 1.6)
I figured if there was a post that went on for weeks just trying to obtain such an item, there would be more of a premium!
PM me with interest!
He has them ready to go, and he will take Paypal!

but, even with all this demand.. our economy is still in the ***ter. and hardly anyone has money to spend. and 300 bucks is quite a bit. but if its good quality parts, then it might be worth it. im just not used to buying parts made out of GOLD. :x
when i built my toyota engine, my pistons cost me 450 bucks, came with rings, pins, clips everything.. and they were even forged. i mean these were the best pistons i could get. and for stock ones at crappa auto, it was 87 bucks or something. but then again, theres alot more 22r's cruising around then there is 1.5's and 1.6's.

he should be lucky to get anything at all... seeing as how 1.5 diesels are rare birds. even though the pistons probably went for $300 a set from the dealer (or higher...)
-
And in all fairness, he may in fact have overpaid for this particular lot of stuff,
but I thought if ever there were a place where one might sell NOS 1.5 pistons in all sizes, I figured it would be here!
let me know if I can help!
Thanks!
