Help ID this piston, block, and head gasket

[87octane]

No automatic. 5 speed Suzuki gear box with 5.13's: 63 mph in 5th gear is all she wrote.

Finally found the block ID pad. Dr. Frankenstein ground off the numbers so you can't read "Abby Normal" (or whatever it used to say...)

Still need to know what IP that is. Anybody recognize it?

And about that head gasket, how many notches? What thickness?

[cyrus #1]

I would say that is a 1 notch head gasket.  According to the Bentley that is for engines with piston protrusion between 0.66mm and 0.86mm on a hydraulic engine.  That is for 1.6 engines though, I'm not sure if the AAZ is exactly the same.

What is the part # on that IP?

just get a proper diesel full engine - this is way too crazy, gasser block, gasser pistons - If you look at the VW white paper on developing the 1.5 diesel, it says that they had to work the engine to very very minute clearances for the diesel compression pressure to accomplish - thats why our diesel pistons use a strut in them and have fused alphin carriers on the top piston ring lands - less expansion and solid design for uber high compression. The liners were hardened also.

Thats why better get a proper AAZ and drop it in there.

I've heard of guys using diesel short blocks for bomb-proof high compression gas engines.  I've never heard of this though...

Does that even work?  that would be one sick gasser lol

and i really dont understand why people try telling other people that their diesel is running rich. they are pure idiots if they think you can run a diesel rich and lean. the amount of fuel going in controls engine speed, not mixture. there is no fuel ever introduced to the intake charge until its compressed in the cylinder and is almost to top dead center.

AMEN !

Not sure, but I'm about to find out. Just got some oversized 1500cc gasser pistons, 76.95 to go in an 11mm headbolt 1.6D block and crank I have. Planning to use the diesel rods to get some piston protrusion, shooting for 15:1 static compression or so. Building a dedicated E85 engine, so dynamic will be down in the 13:1 area to run 105 Octane E85.

after seeing that...got me thinking...Ive got a nice AAZ shortblock...find a 2.0L head and see what happens

[lovinthedeez]

I thought I was on the vortex side of the webs when I saw those 16v pistons.  that guy musta had alot of parts kicking around to come up with that one.  must have sounded wonderful topping out at 63 .

[zukgod1]

I'm just shocked it ran at all really..

I have a 1.6 TD engine about 60 miles south of SLC if you REALLY need one..

that really doesnt look like a diesel block. and since you cant tell and it has no nothing anywhere, i would just junk it. how are you going to know what to order parts for? im still thinking its a PL 1.8 16v gasser bottom end. and you have no future building a diesel engine out of it if it really is a 16v short block.

on another note... you could take an AAZ, bolt a 16v head on it, and then throw about 150 horsepower worth of LOL to it.

Without seeing the engine displacement stamp on the back of the block, I'm tempted to believe that motor is an actual diesel block, perhaps with the 16v pistons.

See that green stripe on the block, that is specific to later hydraulic diesel blocks (1986-up). Early Rabbit blocks were painted all green. Later blocks were black with a green stripe. It's hard to replicate the VW color and pattern. That motor has the paint stripe in the exact spot as diesel blocks. I figure that VW painted all the blocks black, and simply painted the diesel blocks with the stripe to differentiate them, rather than have 2 completely different paint programs.

Given how sloppy our Dr Frankenstein was, I don't think he went thru the trouble of trying to replicate the original paint program. My guess is he bored a 1.6 (TD??) block and was too cheap to buy new pistons and used the 16V pistons. The only odd part is the "Made in Mexico" stamp on the back of the block. AFAIK, all diesels in the US after 1985 had the blocks cast in Germany, and ALL hydro blocks in the US were of German manufacture (they only came in Jettas after 1987, and those were all made in Germany). I think the block may actually come from south of the border.

looks like a gas block and headgasket.

first off both the block and gasket use the locating pins, gas blocks and gaskets use these locating pins.

also if you look at the piston tops, they were getting way too close to the valves, so obviously the gasket was not thick enough.

my guess is that it is a 1.8 gas bottom end with the diesel stuff put into it(im shaft, vac pump etc...) with a diesel head slapped on it.

interesting idea actually...

[smutts]

It LIVED?!!!!!! Even twitched would have been a suprise!

I can't work out whether to laugh till I puke at the absurdity of it, or send my condolences, or shiver with fear that I will one day meet a similar lunatic Frankenstein.

That does look quite like a 1.8 block.  Here are some pictures of mine when it was apart.  Note the alignment pins and the extra coolant passages between the cylinders.



I'm pretty sure that's a diesel head gasket though.  It appears to have the metal re-enforcement for the swirl chambers.
