Smog pump bracket engine install advice or tips sought for neophyte

[mike sampsel]

I remember how the ear on my smog pump caught, under the shelf which holds the motor mount, during engine lift after a partial engine drop. I shuddered as it lifted the whole car. I solved it with a Big Screwdriver prying on the ear pushing the engine back Towards the front while pumping on my Jack. Is there a more elegant way to install the engine transmission pair?


The pic shows (red circle) the bracket ear and the motor mount shelf with engine installed. This neophyte is just trying to preempt panic on future install

There is no other way. Your SC enging-gearbox combo needs to tilt up, go forward, and then the rear raised to complete the install. Somewhere during the process, you need to make sure it clears the rear side of the body.

Possibly the smarter way would be to install the smog pump after the motor is in position. Goes on and off relatively easy.

It's not the pump itself, it's the bracket. This is not an easy on/off.
Thanks though

Mike ,why do you have a smog pump??it is only good if you are going for test...no other reason,really.
Plus replace your engine mounts they are shut!!

I just ordered new engine mounts Ivan. Glad you confirmed my thoughts there! So the smog pump does not reduce emissions?

[proporsche]

Believe me it has little effect if that is what you are worried about....i assume you are inCA?
What effect it has is, your engine sounds and running of it ..just take it of;-)

Should I plug the big hose with a cork, and the one vacuum line to the throttle body just cap it off at the throttle body? Then take of the smog pump and store it in safe place (I'm sure it is quite valuable LOL).

[proporsche]

yes do all that..do you have to do a smog test every 2 years..?

No, no test

[HaroldMHedge]

If you are pulling the smog pump, why not the air injector lines and valves. Then install plugs in the heads to fully remove the system.

[proporsche]

in that case do as Harold said.Remove the christmas tree(that how we called in in the 1980) and plug the cyl heads with special copper bolts made for it..i see no more copper but here.
Also all the unnecessary vacuum and egr valve.

Ivan, What was wrong with these?

[mike sampsel]

Seems removing the Christmas tree might make sale of car to a CA buyer difficult. So I’m not likely to do it. I’ve removed my pump and I plugged the big hose with a cork and that’s all for now.

Wonder if the yoke can be removed after an engine pull?

[proporsche]

Hi Mike..you can remove the yoke even with the engine in.
The mounts are gone as you can see the rubber is collapsed...mainly the left one...keep the right as an emergency spare....

Thanks Ivan,

I replaced my motor mounts with new ones.
Was joking about the old ones.

Wonder how many nuts and bolts hold the yoke?
I took off the two obvious ones which held on smog pump related items, and yoke is still very firmly attached (at least it seems).

[proporsche]

there are 3 nuts.But first remove the EGR valve with the hose and store it.It holds on bottom with hose clamp and lift it up from the shroud.it is part of the metal bracket.Once you remove it you will see the 3rd nut.Then slide the bracket out and replace the 2 upper nuts back so they hold the chain housing cover.Of course if you are planing to sell the 911 you keep the xmass tree pipes but you can remove it and store it.If you sell to CA the new owner can put it on himself;-)
Also the bottom stud you can remove it has no effect on the cover....

it's been years, but I used to swap SSI's out for the stock exhaust every two years and recall remove/replace the pump mount w/o any real difficulty with the motor in the car. regarding removing the spider manifold that supplies the forced air to the exhaust side of the heads there is a 914 brake caliper part that works well. I agree copper is nice, but with some antiseize the steel 914 parts came out every two years w/o issue.


have you run the car with the lines simply plugged? seems like the pressure generated from the exhaust side through the spider manifold could be high?? ive heard of times where the plug came out of the heads and it got very loud in a hurry
