Is this exhaust manifold gasket OK?

[MikeDobbs]

I just unboxed a new Mercruiser Exhaust manifold for my 3.0lx engine, and the gasket was a little bent from the shipping. I'm new to this, and my first reaction was to call my marina and tell them it was damaged and I needed a new one. But, the parts guy has gone home, and now I'm wondering if I'm making something out of nothing. Could you take a look and tell me if this gasket is OK? It was bent a little in two different spots. I sort of bent it back and flattened it in my hand, so it looks better now than it first did. I really want to get this done tomorrow, but I don't want to put a gasket on that will cause me problems down the road.

Thanks in advance.

Those gaskets are pretty rugged in a good way. Yours looks usable to me.:encouragement:

Usable sounds like it would work, but may be sub-optimal. If they can't get me a new one, I can cough up $15 for another one from a different marina and try to work it out later. I''d rather pay another 15, if it might be iffy

I would use it and not bat an eye

Here's some other photos of your gasket part number that may help you decide if you'd like to use the one you have or not. http://www.ebay.com/sch/i.html?_fro...1313.TR0.TRC0.H0.TRS0&_nkw=27-815528&_sacat=0

Those longer graphite type gaskets do tend to develop the crinkled appearance due to mishandling, not being hung up on a wall vs being thrown on a shelf laying over half an item causing a bend to the other half due to no support, etc.

Yeah, that's going to seal fine around the exhaust passages. Torque it from the center out, 2 or 3 steps to full value.

Mec 3.0lx exhaust manifold torque specs?

Hey everyone,

Installing a new exhaust manifold and elbow tomorrow and I can't find the installation instructions in the manual I have. It says to refer to section 7B, but it's missing from the PDF. Does anyone have a working link to a full manual, or can anyone help me out with the correct torque on the manifold bolts? I'd like to try to get this right : )

23 ft. lb. starting in the center working outwards. Also the OEM service manual # 13 say after engine has been brought up to temp, allow engine to cool and Re-torque manifold fasteners.

Also I'm going to move this topic over with your manifold gasket question to keep it all together since it's pretty much the same area of the engine you're working on.

One more question- There are 3 studs which fasten with nuts on the other end, and two bolts in the kit. Does anyone know where the three studs go as opposed to the 2 bolts? Does it matter?

Say we number the mounting holes in this picture from 1 to 5, left to right. Where should the two bolts go?

Nevermind- I just realized I can go look at the block and see where the old mounting studs are.
