Okay peeps... we pulled the engine out of the GLI tonight, and I got some pictures of the head... I was hoping that you petrol dubbers could tell me if this is a bad sign, or what... I don't know what do think, like mabey it warped the head or whatever. None of the valves are bent (thank ***).

If you will notice on those 3 pictures the scarring in the combustion chamber part of the head, the cylinder threw a rod, and the piston extended up into "no man's(pistons) land" and did a number on the head on that portion. Whaddaya think?

Here's some other pictures:

-------------------------------------------

On a completely different note, I don't know what to think about the block. I am fairly certain that the block has sustained some dammage from the motor being blown. I have heard lots of crap about adding a 16V head to an 8V engine. Well, there really is only one difference I see between the 8V and 16V. The pistons. I mean there are misc items like the dizzy is on the head instead of on the block, there are some small differences, but for the most part, I think the block is the exact same. It's a 1.8L block, and it appears to be machined the exact same. Which leads me to my next question. If I equip one of my 8V digifant blocks with all the trimmings of the 16V would it work? I am 100% certain the crankshaft is dammaged, so could I simply add rods and pistsons from a 16V engine onto the crankshaft of an 8V, and stick it in an 8V block? I have not torn apart the block yet to inspect the dammage, but I am sure it is really bad. From the looks of it, the cylinder wall did not sustain any dammage. Only tearing the block apart will tell if I can use any of the parts or not.

Where can I buy 16V engine parts?

Any comments or suggestions would be very helpfull. I have NEVER worked on a 16V before and I am scared to death.

thanks peeps.

Wow, this is my first time looking at a 16V head up close. Look at where those plugs are located! Interesting.

I'm going to have to say scrap it and stick with the diesel. <-- that comment has nothing to due with the condition of the engine, as you probably know more then I do about it. It is soley based on the awesomeness of diesel :D

Honestly, it looks "iffy" at best. I would take it to a good machinist. I recommend Rod at C&T machine in Orem. Very good, honest guy and we've got alot of work done by him. Have him check the damage and he'll tell you the best way to go. He even hot tanked my 1.8 head for free so we could better examine it. Combustion chaber damage is nothing insignificant. it should be smoothed up or it could create a "hot spot" and cause pre-ignition. If you smoothe it out, you will have to 'cc all the chambers and match them. If my car keeps pissing me off I might have a 2.0 bottom end you could use. It's about to get death by sawzall! If you used 9a pistons (from a 2.0 16v) the compression would be about right. If you used the 8v pistons, comp. would be good for boost :twisted: Just remember, if you get the timing belt/chain off a tooth or two you will hear some BAD noises! 16v's are interference engines!

Diesel = Cool

Cool + 53hp * Mr Diesel's idea of a fun drive = Boring

Boring = Bad

Bad = Time for swap.

The dammage is purely cosmetic... you can run your finger across the dammage and it's totally smooth, but it looks bad. the 2.0L bottom end with 16V head causes a compression ratio of 8:1 i hear...

I would still take it to Rod. Doesnt cost anything for a diagnosis. it would also be a good idea to check for straightness and deck the head.

Compression would be exactly the same with a 1.8 8v bottom end!

yup.. I can't argue with that logic, although

cool * ticket + jail time = someone's new wife
