Honest to god since my last post, ive been looking at the available diagrams of the 1.6 motor through the link to the other site and i have no idea wtf im looking at. Im trying so hard to comprehend how the wiring is done in the motor area, looking at the legend, checking out the wire colors, REALLY trying here but i just dont get it... for whatever reason the car wont turn over and i think its because of these two wires.

On a serious note, I don't have a 1.6 or I would go take a look to compare.

Plugs in that area are CAS, coil pack, injectors, coolant sensors etc. I will have a look for you later this morning, the small connector looks like one of the coolant sensor wires at the very back of the engine.

You say it wont turn over? Even without these plugs connected it should still turn over, have you connected the starter motor and do you have a good battery? Are all your engine grounds connected?

ReaperofMiatas 05-10-2012 06:05 PM

Thanks Baz you were rite about the coil pack/coolant sensor connectors, felt around the back of the motor and found it. As for the battery had that tested and it was dead so now its on the over night charge in the parts store hopefully it will be good to go tomorrow.

So is it a crank or is it a click or what was the problem?

ReaperofMiatas 05-10-2012 07:58 PM

If your talking about when i tryed to start the motor with the bad battery it was a clicking sound.

Late pictures of the gaskets, rings, seals ect... only thing not in the picture was the magan motor mounts. I know not as good to look at as a new shiny turbo or sick looking coilover and rim combo. Baby step ppl not all of us have money in the bank... shoot i dont even have a bank account lol

ReaperofMiatas 05-12-2012 11:29 AM

put in the battery and the cars starts but wont stay on, i turn the key and it turns over no need to pump the gas or anything but it just wont stay on its like maybe 3secs then turns off. If i hold the gas slightly down and hold it at 1500 rmp its fine but after i let go its dies.

No knocking sounds or anything alarming, but there is ALOT of white smoke out the back like it did before the headgasket change, but i was told thats normal for a rebuilt engine in the first few miles. What do you guys think? Should i try to upload videos, and if you want videos what should i video tape? Any advice would be welcomed.

ReaperofMiatas 05-13-2012 07:28 PM

Turns out that the timing was off slightly, turns over like a charm. On a side note its smoking like it has a blown HG because... (rolling snare drum) thats rite it does have a blown HG but not really blown tho, i think i just f'ed up the install.

And im not totally sure why seeing as how i put it on just like all the other gaskets only thing i did differently was someone told me to use a special yellow gasket sealant instead of the usual gray.

From your small blurry pic, I think the middle one is the oil pressure sensor, below the intake manifold.

The other one is possibly the coolant sensor plug, on the back of the head. Do yourself a favor and remove your coils before attempting to reattach it. It's supposed to be green though, and yours looks black, could be grease.

ReaperofMiatas 05-19-2012 05:46 PM

Thank you curly your rite but baz already answerd that for me.

I opened the head again coolant on the pistons again but the HG looked completly sealed from what i could tell. Replaced it anyways closed it up and turned her over. STILL SMOKING i dont understand what is doing this. The machine shop told me the head was good. What else could cause this? I know im just an unworthy noob but im out of ideas here.

BogusSVO 05-20-2012 08:47 PM

Grab the bill on the head the machine shop gave you.
Post a pic of the invoice or list out the line items.

The head was checked for warp?
The HG surfaced milled?
Head pressure tested?

ReaperofMiatas 05-21-2012 05:18 PM

Will Do!

Another person told me since i didnt drive it for longer then 10 min that maybe, there is leftover antifreeze in the catalyticz converter from the original HG, and it just needs to be burnt out.

Dont know how true that can be sounds like BS to me man.

BogusSVO 05-21-2012 06:56 PM

Yes that can happen, coolet puddled in the exhaust.

But you said you say it on top the pistons still. Not good.

Gasket did not seal or flubbed the install.

MLS HG with a belt surface finish.

Cracked head or cracked Block.

IDK if this is possiable on yours, but a rotted out water passage that goes thu the TB for pre heating in cold months.

That is a definite possibility. I had a turbo oil seal fail on my DSM and it smoked for about a week after it was replaced (less and less as it went).

It's hard to judge without seeing how much smoke there is, but there is definite possibility that it could be residue left in the exhaust. Drive it some more and see if the smoke decreases. As long as it doesn't get hot and there is coolant in the car you really aren't hurting anything.

ReaperofMiatas 05-21-2012 09:07 PM

I should just drive it around for a week, and hope all the smoke goes away.The worst/best case scenario i buy a 1.8, and part out 1.6 in the long run. Im going to take pictures of the smoke.

When i first got the block i asked about the huge hoe on the inside of Cylinder wall in #4. It went from the middle all the way to the cylinder wall. But not through it the wall looked fine, and so did everything else in there. I was told its an oil return.

BogusSVO 05-22-2012 10:26 AM

Yes looks like they did a pressure test and surface.

Did you get a pic of the surfae finish before you installed it?

What gasket did you use?

NJN..... yes a oil coated exhaust can take a week to burn off. Reaper is having water issues, and water will burn off much qucker than oil
