Default intake refresh or tb refresh first

I am going to do both, but trying to keep the car in as much as one piece as possible. Just finishing valve covers, and thinking the intake first, but do not want to back track to much. Car is an 89 gt.

Thank You

That's a question about choosing your poison. The risks of not doing each one really depend on your risk tolerance.

If you don't do the intake refresh and have a fire, you could be risking more than just your car. If you don't do the TB you could risk some valves and potentially the engine I guess.

fuel lines and T-Belt, then intake.
No back tracking involved

Also the car won't be driven in between procedures. Just wanted to keep it to more of a couple small projects, instead of one massive, never see the end job. I get sidetracked with other projects a lot. And a supercharger on top of that. Plus sometime going to the body shop.

If you aren't driving between procedures then there's no order-of-work worry. But there are some things that make a one-time effort look pretty good. Cam chains (between the intake and exhaust cams) get replacd as part of top-end refresh, as do front cam seals and the cam end plugs. So the gears are off and the front cam drive bits are off. Perfect time to fit a new belt. The cam position sensor is easier to replace with the cam covers off. So my vote is to do the cam covers, cam drive and seals. and the timing belt as one project. If the total scope includes powder-coating the intake and cam covers, it makes sense to have the intake off for refinishing at the same time as the covers are done.

I roughly did the following: remove all TB items, then all intake / cam items, send intake stuff to powder coat, then clean everything on the block and everything I took off which was going back, repair/replace all intake/cam items and reinstall, then do the TB stuff to complete. See my below link to Photobucket for a pictorial from beginning to end.

All gotta be done but fuel lines should be first. Search for Dwayne's excellent write ups. Back fuel lines (U line between rear dampers and FPR, return line) might be easier to access with intake off but doable with it on. Also check the CPS and knock sensors while intake is off.

Is the Cam and Hall switch the same?

I did the cam covers first so that the cams would not be exposed very long.

I can powder coat at home.

Yeah might make sense to just tackle it all at once.

They turn out ok I redid them 3 times.

There is no cam switch. There is a hall sensor and two knock sensors.

The cam covers look very nice!
