Heat riser removal.
'91 Sport Sedan, 5mt. Is it neccessary to have the heat riser-shielding(correct name?) installed on the turbo? It looks like it would be easier to check for oil leaks and to see joints in that area better if it was removed. Your thoughts, advice is appreciated.

If you do remove it, you might never get it installed securely again. I removed mine once and the bolts now won't tighten very far because the internal threads are rusty, so the chimney vibrates around 3000 rpm, much to my annoyance.
Its purpose is to shield the rest of the engine bay from the heat of the turbo and to direct cool air from the hood scoop down towards the turbo.

I wouldn't take any of the bolts out that hold it on.Dizzy wrote:It's not necessary, but I think it's good to have it there. If you want easy access, you could remove the hard to get to bolts, leaving the easy ones for quick removal.
I would keep it.
I had a very severe rattle at 2800-3500 rpm once and thought it was my heatshield on my old cat but it ended up being my turbo chimney had a single bolt missing. Replaced the bolt and never had a problem again until I decidede to remove it.
kleinkid, I would keep it on unless your running an after market DP that doesn't allow you to keep it (which is the reason I removed mine) or a bigger turbo.

unless you plan on changing the turbo or adding an intercooler then I'd leave it there. Contrary to what most people think, its there to vent hot air surrounding the turbo up out of the engine bay and out of the scoop in traffic or when parked.
