Hi i'm in the garage and going to tight my head, does someone have a link for doing it right? i don't have the Hayens og bentley here, and a pic of the right sequence of tighting it!

instructions here. Its exactly the same as what bently says.

Oh, chase those threads first.
I like to wait till the last possible moment to do the final 1/2 turn so that if you have to pull the head for any reason you dont have to buy new bolts.
-
thank you, reading this:
On diesel engines, reinstall the combustion pre-chamber inserts, if
they were removed while cleaning the cylinder head.
what part is that? :roll:
Three different cylinder head gaskets are available for use on diesel
engines, identified by a number of notches or holes in the gasket near
the part number.
omg i didn't know that, checked my old gasket and got 3 holes, the new one got 1, how ***ed am i? :evil:
-
That's bad news. The different gaskets are different compression ratios. The more holes, the thicker the gasket. If you run a gasket too thin your pistons can contact the valves even during normal operations, not to mention your compression will be through the roof (not good on a turbo diesel).

Holy crap don't even tighten the head down!!! You need to use the correct headgasket, three hole.
What year is your TD? If it's 86+, buy a 1.9TD 3 hole headgasket (not a 1.9TDI), it's the same thickness as a 3 hole 1.6 HG. It's a metal HG, much better than the fiber gasket that is stock on 1.6 diesels.

Thanks! i'm not sure what year the engine is, someone told me that the engine is not a original TD since my diesel pump does not have the UFO at the top, but i'm not so sure about that. But how do i time these engines? I can not see any timing mark on the camshaft, i even took of the camshaft wheel (yes i marked the timing belt :) ) and look for a mark and discovered that the wheel can fit around the camshaft any where, i'm used to petrol engine and they can only fit one place. But i'll order 1.9TD 3 hole gasket tomorrow! Thank you everyone!
-
There is no timing mark on the camshaft so to say.
There is a slot in the end of it which should be parallel to the surface of the cylinder head where the valve cover gasket goes. Cam lobes #1 and #2 (Sprocket end) should be pointing at 10 and 2, and the last two lobes (Flywheel end) should be pointing at 8 and 4. The injection pump sprocket should be lined up with the mark on the injection pump bracket, or the metal backing plate if the later A2 design, and flywheel should be at TDC as indicated by the TDC mark.

Thank you, i'll check this out, yes i got mark on he plate that holds the pump and on the pump...

On diesel engines, reinstall the combustion pre-chamber inserts, if
they were removed while cleaning the cylinder head.
What is that, where is it located, and what does it look like?

even if a 3 notch was on before, i would still measure piston protrusion because maybe you need to use a 2 notch or even a 1 notch to get it to run properly (they will all run with a 3 notch, but cold starting will suffer)

Look at this pics, the pre-chamber is located to the left of the valves (round thing with a semi-circular hole in it). You most likely didn't remove them, they need to be punched out from the injector hole.

thank you very much for good information, i did not remove them :) I ordered the 1.9TD gasket and it didn't fit... realizing that my engine is older than 86. I'm starting to think maybe its not a original turbo engine at all? or? I'm going to take a picture and write the numbers on my pump so maybe someone here can identify it and confirm. Thank you guys again for this help!

the 1.9 gasket only works if you have an hydraulic head. 1986.5 and newer.

My head is hydraulic but the bottom was wrong...?! The head is not mechanical...
-
Are you sure? Do you have aftermarket head?
1,9 HG will fit directly to engines with hydraulic lifters. You can easily make it fit to solid lifter engine too, just block the extra hole with piece of rubber.
There is original turbo engines with solid lifters from factory.

Hydraulic does not have visible springs right? they got this call "pusher" above/around the spring right? Thats what i have, and the guy at the shop came with a head gasket that was the same as my old gasket and he told me that this one was before 86 or something.
-

i had a factory original 1.6TD mech engine in an 86. last year that they sold mech engines. I must say that car had some serious low end grunt. wasn't tuned for revving, but it could haul a car full of 'heavy set' people(5x200lbs or more) and still accelerate as if it was empty, but once 3k rpm hit, there was no balls, so next gear and away she went. :D i still miss that car!!!
you can't use a hydraulic head on a mech block as far as i know.
-
i got a picture I'm gonna upload witch i took with the 1.9 TD gasket and the one i had, i'll try tomorrow.

Look at this pic, see the big hump in the middle between the injectors #2 and #3? If you look to the left, there's another smaller hump between injector 1 and 2. Every hydraulic head has these two humps. If there's only one big hump in the middle, it's a mechanical head.

Mechanical AMC aftermarket heads have two humps. The smaller one is not drilled.

The lifter is above/around valve springs. Mech lifter has separate adjusting blocks between lifter and cam.

Yes looks like the one i got, but on the cam shaft bearings you have 3 bolts in the center, i don't have those...

That's because it's a picture of a 1.9TD head. 1.6TD is pretty much the same except for those studs and intake/exhaust ports.
-
ok i see!
But hey listen up :)
i put my engine back, but apparently when i tried to start the engine the wheel on the camshaft have moved a little because of not tightening it enough, so now my valves has hit the pistons several times, but since the valves goes straight down to the pistons, any of you got experience if i can just time it again and run? Or do you think piston/valves are broken now, i'm not taking it apart to inspect, i'll rather just change the engine to a real 1.6 TD with diesel pump with "UFO"...
-
is this a 1.6D or 1.6TD head?
mechanical or hydro?

1,6 hydro

Finally took some pics of my engine,, i checked the valves and the exhaust valves hit the pistons, but they where ok....

Hope someone can identify witch engine i got, gasket i need to use vas earlier than 86....

You have mech block, head and lifters.
-
Looks like your intake valves on 1 and 4 touched down for sure... did it warp the valve(s) ??

They look ok, and passed my leak test... :)
-
But can someone identify my engine, what model/year if its a original TD or what?
-
The block has a letter code on it just below the head gasket. I was trying to find a pic. I'll keep looking.
The letter code can be desiphered here--->http://www.4crawler.com/Diesel/index.shtml#EngineSpecs
