Thanks!

 

I will try that this w/e.

Well as for the coating and wrapping, I believe it was hughdogz that did this and he cracked his manifold it got so hot. Ill search for the post to confirm my memory.

 

Anyone has a 2nd opinion on whether jet-hot coating the manifold will cause it to crack?

My exhaust manifold is coated inside and out, and the heat shield has a coat of high temp black on it..... no cracks after two years. I was thinking of wrapping the mani as well, but I have seen the aftermath after the wrap is removed... talk about rusty!

Thanks for the input Aarang.

 

In and out it will be then, with grey 2000. Heatshield painted in high temp grey, and no wrap.

Those four bolts below the heat shield that go into the head dont "hold" the manifold on they just "hold" it on. If you remove the 4 bolts on the top of the manifold, two in the middle one on each end, make sure all the fuel lines and vacume lines are detached the manifold will pull strait up off the engine. The bolts you mentioned only wedge the manifold onto the engine, loosening only makes it easier to pull off.

 

It will feel like its impossible to pull off but it is possible. I actually used an engine hoist an a junkyard to pull it off it was on there so tight.

 

Had a look at it over the W/E. If I can get the intake off this way it does not seem like I can replace it like this. 1) Gasket likely to be damaged either when pulling it up or forcing it down. 2) I am uncertain whether forcing it down would also and seat it properly.

 

I think if I can get out the 4 bolts holding the horizontal heatshield, i.e. from the underside of the heatshield, then I can access the 4 bolts "holding" both the intake & exhaust.

 

Checked my Haynes manual again. Nothing on the horizontal heatshield (only mentions a vertical heatshield).

 

Anyone has any idea how best to get at these 4 bolts on the underside of the heatshield, whilst the engine is in the car?

I've done a few intake pulls on turbo vehicles that had that damned heat shield on. It's a real pita.

 

It's darn near impossible to get the heat shield off with the intake on the engine (though I've done it, not worth it). But to keep from ruining a new gasket (old ones will just tear anyways usually) then you need to loosen 6 bolts on the exhaust manifold that are shared between the intake an exhaust.

 

The best way I've found to get to them is using a swivel joint for your ratchet, and have a wide variety of extensions available. It also helps to have two swivel joints if you can. One on the socket end, another on the wrench end. If you have the stock bolts then using a short/non-deep socket helps getting around under there. If you have studs on there instead, then you might need to use a deep socket, which might require putting the socket on first, then getting your swivel into place.

 

Hope that helps.

 

 

...now, the reason I found this thread... Anyone have any suggestions on what to use as a simple filter breather for the PVC plug on the block? My block has been actually MISSING the pipe insert thing for the last who knows how long. I'm temped to just get some copper pipe and put some slits in it, hammer it in, then attach a small filter to the end of the pipe.

 

Sound good?
