I've got an '88 IROC with 305 TPI. The oil pressure sending unit and brass 90* fitting recently broke off while I was trying to remove it and install in my Autometer gauge.

I have tried using Easy-outs and reverse bits, but there is just not enough room to get the broken piece out. My Dad suggests that we pull the engine to gain access to it. I was figuring to remove the A/C, A.I.R, and add some headers whenever i pulled the engine, but hadn't planned to do it so soon...

What I'm really wondering is if there are any write-ups on how to pull the engine?

Thanks!

 

Not really. It's considered a "standard" operation, one that's adequately described in a Haynes shop manual.

There have been discussions of engine only or engine/transmission together, how much of the induction to remove, and that sort of thing. But, the basics of what to unbolt in what order, no.

Pictures before and during taking things apart, labelling wires & bolts, those sorts of thing are good ideas.

 

Alright, thanks for the help.

 

There's no need to do that.

You should be able to remove enough stuff off the top to make it real easy to get in there with an Easy-Out, maybe as far down as the intake but I don't think you'd have to go that far. I'd think if you pulled the plenum, runners, & distributor, it should be a piece of cake.

I HATE EZ-Outs for most uses, because they about always break off in the bolt fragment, when that's what you're using them on. But for a little sleeve of brass, one of those ought to be about perfect.

 

I've been suggesting something like that, but he won't listen..

We have tried EZ-outs and reverse bits, but even when we get it in as far as it'll go, it just ends up tearing out the inside of the fitting.

 

So then, try going with the flow, considering that "tearing out the inside" = removing it piece by piece...

How about a reamer, followed by a 1/8" pipe tap, while keeping a vacuum cleaner focused on it?
