Re: Oil in injector housing?
 

Easy on the Mr.!

I wasn't able to get to a set of 90, 1st design injector housings to measure the washer/baffle hole diameter. However, I did measure the hole diameter in the cylinder heads for 91-95 models, at 7/32" drill. If your's are already drilled @ 1/4", i wouldn't re-do them, but i sure would not go any bigger.

If 7/32" is good for the 91~95, it should be good for the baffle washer too.

How about a photo or two of your fix in progress & the end result for "Mr" Dynomite & me?

I was being the little kid who was in trouble asking the adult for another favor!

Any who here goes nothing....yea, I'm going to try to do this with pictures. Just in case I screw it all up here is the link to my photobucket album!!!

I think I'll post this to see if I screwed it up! oh, the drilled holes are 1/4", but I may go a bit bigger?

Darn....I'm amazed that I got it to work!

This is how I started to install the reshaped plug with the flat bar.

Then I used my other precision tools to recess the plug a la the OEM install. You can see the one on the right is dunn, middle in progress and the left is what the flat bar does.

Then it is supposed to come out looking like this, with a slight recess just like the factory did the real ones!

That is correct

It's there, you just can't see it in your photo. All 3 holes are open in the cylinder head.

That Ball peen hammer has sentimental attachment for me.... :mrgreen:

Anyway not that it isn't fairly obvious, the object is to get the freeze plugs flat enough so you get them to be a tight fit in the large CCV holes in the late model I/H's. These are 91 I/H's.

I used the flat bar & my mini-anvil to take some of the dish out of the plug. You play it by ear, if you go too far I used the ball hammer to reform the cup.

Then I positioned the newly shaped plug over the CCV holes and tapped the bar till the plug is flush all around. Next the socket to get that factory recess look. Don't worry if you knock it thru as you can get them back out and try again. The smaller drifts I used to massage the install! :neutral: to achieve that OEM look....well at least one of them came out that way! :sign10:

The reason that I did all three per side with a 1/4" hole drilled thru them was Jerry posted up that the CCV holes in the head had all three drilled holes. I figure it can't hurt. I have a catch can so I'll mind the amount of oil it catches, which is not much now with stock 90 I/H's on stock 90 heads. Maybe we need more discussion on that fine point? I don't have much to contribute to a discussion on that level.

Anyway, that's the long & the short of it.
