[QUOTE=nellison, Sorry sort of new at this forum thing! I rechecked all the connections and everything with the exception of the aux fan is connected.
The timing marks on everything lined back up after rotating manually. Crankshaft didn't line up with cam marks, seems like it's 180 out of position, but did not notice it until I put the flywheel back on it after everything was buttoned up. Question is how do I rotate this back in line with the timing marks without doing damage? Not sure if these pics will show or not. [/QUOTE]

Nellison,

When you made your mark's at TDC, Are You Sure that you were at TDC on #1 Cylinder on the Compression Stroke, and NOT at TDC on The Exhaust Stroke? It's pretty easy to make this mistake.

Read post # 246

i only used the marks on everything and did not pull a plug so i would assume i was TDC. All 3 marks were lined up perfectly and nothing moved while i was removing or putting back. Just saw that i might have the Cam Shaft Sprockets (EXH) on the wrong sides. Chilton did not show them being marked circles/ovals depending on what side they went to. Will start taking apart tonight..

Nellison,

I would advise to use the Nissan Factory Service Manual. It is a Free Download, just google search Nissan Frontier Factory Service Manual, and you'll find a site that has it. Or you can go to Reliable-Store.com and pay 9 $'s that will get you all the Section's in PDF file's that you can make a folder on your desktop and then download the pdf file's to that folder. Then you can make your own hardcopy by burning that folder to a CD, that will give you a permanent copy of the Nissan Factory Service Manual. That's what I did for my 2013 V6 Frontier.

Good Luck,

Nellison,

Hope the download went good for the Nissan Factory Manual. I alway's like to have more than one so I can validate each other and also sometime's one explain's something a little better than the other.

Also I wanted to bring this to your attention that these engine's are interference, meaning that if the engine is out of adjustment that the Valve's can contact the Pistion's. When everything is in proper adjustment then the Valve's and Piston's will clear each other. You probably allready know that but just in case you didn't I wanted to bring that to your attention. That's what the Fellow in post #246 was talking about when he turned the Crank 30 Degree's, but I reread and he explained it pretty good.

Good Luck

I honestly think that i might be off 1 or maybe 2 teeth. I have it mostly broken back down, should have it apart Thursday. If i take the chain off and move the cams into position then can I move the crank into position to put it back in time?

There's also a Nissan TSB regarding the replacement of the timing chains due to the "whine." It has pictures and is a pretty good read when doing this repair. You can find it in the "knowledge base" section of this website under "service bulletins."

was told by a Nissan mechanic that I could turn everything and get the cams to TDC mark, then remove the chain and move the crank to TDC mark re-install the chain and should be good from there. As long as I am not moving it more than 90 degrees, which there is no way I was off that much, the bottom chain is difficult to see the TDC mark on the oil pump housing. So I think I am 1 tooth off one way or the other on the chain/crank shaft. Does this sound correct to anybody - as far as re-timing?

Nellison,

If you remove the sparkplug's it'll be a lot easier to turn the crank.

Just in case you are not useing a shop mirror, it'll be a lot easier to see with one and also a good shop light or other real good light to shine on the mirror to get a good view of the timeing mark's.

In post 246 the poster turned the crank 30 degree's to keep the piston's and valve's from contacting.

I haven't done this repair so I can only offer helpful tip's, I'm pretty sure that SMJ has done this and can offer good guidance on this.

Good Luck,

Nellison,

Sounds good and you really have my respect for undertakeing this Repair. Just to get to the point of replaceing the part's is a major undertakeing and then to replace everything and get it all back together correctly is another big undertakeing. The closest that I have came to this was replaceing the timeing belt on a B2200 Mazda Truck and assisting Replaceing a HeadGasket on my Tractor that wasn't really successful, and glad that I was assisting rather than doing it by myself.

Please keep us posted on how it is going, cause we all want you to have a successful repair. If you run into a problem, I would try and contact SMJ as he used to be a Master Mechanic with Nissan.

While you are waiting on part's here's a video you might like to watch about Castrol's Magnatec Full Synthetic Oil. I don't know if it is Truthful,, but it convinced me to start useing Magnatec.

YouTube

Regards,
