if you have time and about $100, i highly recommend sending your injectors to witchhunter to have them cleaned and flow-matched. you'll get a printout showing the exact flow of each injector:

Taking the woodruff key out of the shaft for the oil pump is a royal PITA....
Not enough room to work in there and was frozen solid. PB blaster and a lot of "persuasion" it came out but looks a little beat up. Mostly on the top side where I was trying to grip it. Will try to polish it out if not got to buy a new key...

I just cleaned mine up and reused, maybe put the "bad" side towards the crankshaft.

The worst engine I had was when I had to drill a hole into that bad boy, and tap some threads to pry it out. What a PITA.

You can get these keys from Harbor Freight in a set for cheap...

Keith man you are quick...
Thanks for the reply, will put the non damaged side into the shaft and the damaged side up ? or did you mean that the damaged side goes into the shaft ?
There is a H.F about 25 miles away (in the big city !)
pics after sanding, did not want to take off too much material or the key may become too loose to stay in there.

Got the seal out it was a bigger PITA than the key !
After messing around (trying not to damage the housing) I used a 90 deg deremel with a 1/8 bit to drill a hole in the seal (as it is too hard to get a screw started into). put a screw in (carefully) and pulled the seal out.
the sleeve came out easy, cleaned it, it has a circular mark on it from the 'O' ring seal? but I cannot feel it dragging my finger nail across it so I assume it is fine.

Once you get the key out, you can usually use pliers and carefully pull out the oil pump drive sleeve. You can then easily get the seal out.

You may have to clean up the crankshaft around the key, depending on how much "persuasion" you needed to use to get the key out.

Your sleeve looks like mine did the FIRST time I replaced the seal. No fingernail groove either. Guess what I was doing a couple of years later!! I don't want you to buy unnecessary parts.......but, just sayin

BTW the key will be ok, but if you decide to order the sleeve, get a new on and throw the old one in your tool box.

'O' ring in the oil pump assembly ??
When I was cleaning out the oil pump shaft this 'O' ring came out...It is made of a metal spring, I cannot find it in the PET. Any clues?
Thanks Sox

Here is my take on the order of fitment.... Also in the second pic could this be the metal O ring?
Sox
BTW the seal goes the other way pic is wrong...

Duh .....
goes on the inside of the main seal.



The reason i was confused was that, when I put a screw into the old seal to pull it off with the tip of the screw pushed the metal collar O ring out of the back of the old seal and it was on the oil pump shaft and the new seal I got from our hosts here did not have that metal collar in it. I am planning on using the old one in the new seal....
The other 3 seals that came with the same order had the metal collars in them.
Time to ask the customer service about it.

I can't remember specifically if that seal has the spring in it. I will say that I cannot remember a shaft seal like these not having the spring. I would def check with the seller.

The spring is part of the seal, guys...

Don't worry about it, just throw it away and get on with things.

Keith I am doing this with the "living life at a less urgent basis" philosophy , but point taken. I was only firstly trying to understand where that spring ring came from, and secondly why the seal sent to me did not have it in it.
As stated I used the spring ring from the old seal, so the front seals are done. I used a home made contraption to seat the seals see pic.



Got the cam cover on, the gasket did not want to stay flat and as I was putting it on dry per your instructions. It came curled up in a small baggie and wanted to curl up on the cam housing. I finally left it out in the sun for 30 mins and it flattened out.

Well...all front seals done, rollers, tensioners and belts done. I have used the 90 deg finger twist method to tighten them temporarily as I await the the arrival of the ArnWorx tension measurement tool.
On to the other projects.
Thanks to everyone for the assist during this process.
