I have my 22RE torn down replacing the HG. I currently have 180k on the clock. I tore it down b/c of the timing guides. I decided to go ahead and pull the head and have a valve job done and new valve seals.

I have a couple of questions for reassembly:

1. I have to get new injector seals/grommets for the intake, do I need to replace the o-rings on the injectors as well??? Also, the dealer said that there is an upper seal that goes in the fuel rail, is this so??? If so, does it need replaced too??? Anybody know where I can get the seals cheap??? So far, Advance auto is more expensive than the dealer @ almost $8.00 per injector for all seals needed.:confused:

2. I was wondering what order that I put everything back together... I had to pull the pan to remove the broken guide pcs. I was thinking that I put the head on 1st. and torque to specs., then the new D.O.A. timing kit and timing cover, and finally the oil pan. Or should I put on the oil pan before the timing cover and just put a little 'import gray' on the edge of the oil pan before I slide the timing cover btw. the head and oil pan??? Any thoughts, suggestions would be appreciated.:confused:

Thanx,
Vince:D

1. I sent my injectors off to RC Engineering to get cleaned and tested and they came back with nice new o-rings. I didn't replace the upper seals, if intact they should be OK.

2. I put the oil pan on last when I put my engine back together: http://4crawler.cruiserpages.com/4x4/CheapTricks/EngineMods/index.shtml

Given the cost of a complete new engine, plus you got 180K out of the last set, I personally wouldn't hesitate to get all new seals. I would also recommend sending the injectors out for cleaning and balancing.

You can really do it in either order, but I prefer to go top-down. Install the head first, then work your way down. It's a lot easier to get the chain threaded onto the cam sprocket, through the guides, and around the tensioner this way. BTW, I had a lot of problems getting the DOA timing cover gaskets to fit properly, so I threw them away and got some from the dealer, they fit perfectly.

1) I second getting new seals from the dealer. Why not - you're in there - might as well do it right. I sent my injector's off to RC to have them rebuilt and balanced.

2) I put my chain guides, chain, and timing cover on first - held the cam sprocket onto the chain with zip ties. Then I put the head on and popped the cam sprocket on the cam. I thought it was easier that way. But you need to keep tension on the chain or it will pop off the lower sprocket while you are feeding the cam sprocket through the head and onto the cam.

I tried to put the pan on first and I couldnt get the front cover in between the head and the pan. Had to take it all apart

Plus if you drop something in there, you have to pull it off, too. Easiest to do last and you get a better seal with the FIPG or RTV sealant if you don't use a gasket.

when you do put the head on, MAKE SURE up put a nice fat bead of rtv sealer on the top of the timing chain cover,....if you don't it WILL leak.

good luck!!
