Yeah, that was my initial thought too, but I got a bit scared to deal with a $1200 set of injectors...

So, what is the trick to getting them out of the rail unharmed?


Checked the trash bag this morning and found 1 compression ring of the gasket to be missing. That was a relief!

Also, I spent quite a bit of time last night cleaning one of the rocker arms. I used a combo of seafoam with a brush and some carb cleaner. Took ages and I am not all that happy yet with the results. How would you recommend doing that? I still have one to go...

Also, need to get going on the pistons this pm. Any suggestions? How abrasive can you get, and how strong of a chemical can you use?

Here is a helpful tip when you put the valve cover gaskets back on. Even if you are installing new ones you will most likely have to the take the valve covers off again for whatever reason.

Put a light coat of RTV around the edges of the compression washers to help keep them in place. It really does work and gives you peace of mind that you didn't drop a piece of brass into the engine. Still can't believe they are that poorly designed that they fall out like that, even the aftermarket gaskets do it.

Valve covers are harder to put on than the cylinder heads.
I am not kidding.

I found I had to

Clean the valve covers to spotless to get off the grease inside and out.

use aircraft sealer from the autoparts store to glue the gaskets to the valve cover. Aviation gasket sealer. If it works in planes, it will work in the Rover.

Good idea on using RTV on the round washer / spacers!!! I did not do that.. That saves a lot of worry. As those round cylinders just fall out - onto the ground. Into the engine.

Then putting those back on - wiggling them all around to get the bolts to even line up.

Then, the gasket slips off the cover.
And, you need to use feel of finger to make sure the bead is lined up.

You tighten it snug. Until the valve cover engages the round cylinder spacers.
Too tight - snap!

This in the MOST FUN you'll have for an hour or more.

It's not harm to the injectors, it's corrosion in the fuel rail cups, at least that's been my experience.
My '95 was always a southern car, so no rust in general, but the rail cups were.

I use Purple Power for cleaning parts. It's corrosive to aluminum though so don't leave it in for more than a couple of hours. I accidentally left a bellhousing bottom cover plate in for a few weeks. It wasn't pretty.
