my 86 pirelli 4 door gas to diesel build

Does your tach work with the diesel engine?

Does your tach work with the diesel engine?

nope, not yet. been trying to find a ce1 diesel cluster first before I get on that project.  I've been driving standard cars; diesel's lately, all my life, and I don't think there is any need for a tach anymore.  If I can't find one, I'm putting a clock back in.

decided I was tired at looking at this brand new water pump for the old gasser that was in the car before, and put it in today.  water was a nasty brownish color.  needed a good flush.  the temp was kinda all over the place before, but it seems like it is running a little hotter than before, staying in pretty much the same spot all the time.  the thermostat already in the housing was for the gasser.  I didn't have time to get a new thermostat before I needed the car, so I just used it as it was.  gonna get the diesel thermostat tomorrow and see where she runs.  pump definitely looked like the original one.     need to pull the aluminum thermostat housing off of it, and replace my crappy plastic one.

Now you need a turbo and intercooler!

yup, someday.  I just found out the "new" waterpump i just put in had a bad bearing, which burst my middle waterpump hose.  found this out on my trip down to the sf bay to see a concert with the fam.  130 miles into the trip, that happened.  spent all day trying to put a new pump on, when I found the housing was cracked pretty good.  sad thing is I threw away my old pump, which had a perfect housing.  jb welded the housing, and limped it back home 140 miles with the radiator cap off so I could keep refilling it.  amazed I didn't blow the motor.

dang... that really sucks.

[lovinthedeez]

this overheating is KILLING me (stolen from the troubleshooting section )
so before I hear the usual, let me explain what I have, and what I know.
swapped 1.6 n/a from 81 rabbit into a 86 jetta
still have the gasser exhaust from the manifold back
still using the gasser radiator from the jetta
never had a problem until i put in a new ( which turned out to be bad) water pump

car runs fine, even when getting hot.  no smoke or anything
seems to run a little cooler when I leave the exp tank cap off.  this makes me think head gasket.  but if it is, shouldn't it be smoking, or not running right.  the thing is that it runs FINE.  no noticeable difference other than the temp guage.  I live in a small town, and have been taking it all over the valley without a single snafu.  however lately, it seems at the guage level to be overheating.  I guess what I'm asking here is, is a couple of things

what would be the symptoms of a clogged gasser cc?
if blown hg, why running fine and no smoke: esp the cap on/off thing.
radiator plugged?

just getting real frustated.  gonna drop the oil in the next couple of days.
a link to what seems to be causing all my recent headaches.

I'm blown away by the fact it runs fine sometimes, and sometimes the temp guage will shoot straight to the top after only a couple of miles, but still run fine.

mine ran great....and I mean really really great.....HG was blown in 4 spots ....the longer I drove it the more I noticed it was dropping off on performance...I was really surprised that mine ran so good with a blown HG...mine did not even over heat really...just kept puking coolant out the expansion tank.

how does a bad water pump bearing blow a hose?

pulled this from your other post..
"made it home 109 miles back over the mountains home, and the engine running decently.....just freaking hot"

how hot is FREAKING HOT?

best way to check your HG is to take it to a emissions shop and have them sniff the coolant expansion tank for hydrocarbons..

[lovinthedeez]

freaking hot meant the needle was just about pegged the entire trip home.  kept stopping to put a little more water in it.  I don't know if the water pump caused the hose to blow.  It was just kinda funny to actually see it blow and pee all over my foot like that.  I can kinda smell the HC through the expansion tank.  It must be the HG.  can't see it being anything else at this point.  I am just amazed at how well it runs with a blown headgasket, that's all.  Either that or my head is fubar.  either way, I see my little motor coming apart in the near future anyhow.  not a big deal, as I work five blocks from home, and I don't really need a car.  The little lady has her own.  now if someone has a td just sitting around, could I please has it, pleeeeeasssssssssse .

[Rabbit on Roids]

i have BUNCHES of stock TD parts i will never use.. you are close, so i could make you a smokin deal if you wanted some of the pieces. i dont have a turbo oil pan, return line or feed line, or the turbo. but i have all the manifolds and important stuff.

and about your headgasket, they run fine with blown gaskets. i blew a HG once, put a new one down, and it wouldnt seal. pulled it back apart, and voila, the driver side of the block was pretty much cracked off, but it still ran great!

[lovinthedeez]

finally got the motivation to get going on this since my motorbike wrecked its clutch.   So went to pull the head today, and got as far are pretty much having everything unhooked minues the injector lines and plug wires.  lots of room to work and everything went smooth on disassembly, as it should have. 




more pics to come in when the head comes off.....hopefully nothing but a headgasket. 

 

[lovinthedeez]

so I got the head off today, and was actually kinda happy at what I saw.  from before, I was overheating very quickly with puking out the coolant reservoir after only a couple of miles of driving.  After limping 140 miles over the mountains running as hot as it was, i still won't be surprised if I cracked the block or head.  but all I found after tearing off the head was a blown headgasket between at the #1 cylinder, and some pretty gnarly almost blocked off coolant passages.  pistons had only a thin layer of carbon which wiped off with just a rag.  bores look 2XX,XXX miles old, but still really nice.  from the look of the ridges, I doubt it has been bored at all, which might come in handy later.  ordered all the parts today, so that will give me a couple of days to clean it up real nice.  a couple of pics of what I found;  my camera blows so go easy on me

gasket still on the block.  looks like the p/o wasn't too keen on coolant changes over the 13 years he had it



so (I think) it looks like a failure between #1 and 2.  didn't really know why the oil is at the upper #3 bolt hole, but I figured it was just because maybe the gasket blew near there too?


head looks alright for the most part.  cracks seem a little worse on 1 and 4.  a better head is definitely on the shopping list now.


pics make it look worse than it really is.  I think its gonna clean up very nicely tomorrow.......

[lovinthedeez]

sooooooo.......after looking at the pics once again, i'm getting a little scared, actually just paranoid.  why is oil there on the bolt hole beneath the #3 cylinder on the block pic.  If the block was cracked, it wasn't because of me, because
1.  this motor hasn't been cracked open for at least 100K miles(when p/o did a re-ring)
2.  I though the infamous cracked block came from re-installing the head
3.  It ran great the last two years I've been dailying this motor in two different cars, up until the day the wp went.
4.  its a 11mm head.......

paranoid yes; scared, no.....
we'll see what 50 bucks in parts is gonna do.  more to come

Can you see all 4 photos you posted yesterday? I can only see the 2nd and 4th.  So, I can't see what you are asking about. 

[lovinthedeez]

I have a few days until my parts get here, and I have the next two days off.  plenty of time to clean that dirty little puppy up.  and with the head off, I think its time to put my shifter rebuild stuff in seeing there is sooooo much room to work down there now.  good to hear that the oil around that bolt hole is no biggy.  I kinda figured it was nothing at first, and then started second guessing myself .  now to get off my butt and to the store to get some stuffs.
