need4speed Posted May 18, 2015 Share Posted May 18, 2015 Can anyone recommend the best exhaust manifold gaskets to use? I have the type pictured below and the fit is nothing short of awful. Quote Link to comment Share on other sites More sharing options...
elbekko Posted May 18, 2015 Share Posted May 18, 2015 The stamped metal ones work as well as an RV8 exhaust gasket they ever will. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted May 18, 2015 Share Posted May 18, 2015 I hate the stamped ones, could never get them to seal properly, and sliced your fingers every time you went near them. The only ones I have foudn that reliably seal are these: http://www.ebay.co.uk/itm/ROVER-V8-BIG-BORE-EXHAUST-MANIFOLD-GASKETS-X-4-/120495446055?pt=LH_DefaultDomain_3&hash=item1c0e169827 They are similar to yours, but have a metal piece on the inside of the port to stop burn-through. Here's another: http://www.ebay.co.uk/itm/LAND-RANGE-ROVER-V8-EXHAUST-MANIFOLD-GASKET-SET-3-5-3-9-4-0-4-2-4-6L-/201032247979?pt=LH_DefaultDomain_3&hash=item2ece74aaab Quote Link to comment Share on other sites More sharing options...

Just ordered a set of the stamped kind earlier I have studs fitted so maybe I will be ok as I can see if they're perfectly centered before I offer up manifolds. If not I will get the kind you referred to Bowie... Quote Link to comment Share on other sites More sharing options...
JeffR Posted May 18, 2015 Share Posted May 18, 2015 The stamped metal ones work quite well if you buy more than you need and split two of them so that you effectively have 3 pieces to each gasket! Quote Link to comment Share on other sites More sharing options...

JeffR Posted May 18, 2015 Share Posted May 18, 2015 Say what? If you look at the stamped metal gaskets, they are made of two or three thin bits of metal spot welded (well somehow attached to each other) together. I found that such a gasket was simply not up to the job when one blew out whilst away from home and halfway up a Scottish track, in my emergency spares I had a spare single gasket (got no idea why) so I split it into it's separate parts and put an extra "leaf" on the one which had blown, it lasted about 70K miles! I think that they are simply not thick enough or flexible enough as they come to allow for the variations in both the cylinder head and the manifold - probably not describing this very well, but if you take one apart you will see what I mean - I'm referring to the stamped metal hobbies not the fibre things you put a photo of.

need4speed Posted May 18, 2015 Author Share Posted May 18, 2015 Sounds like I've made a mistake buying the stamped metal kind. Looks as though I will need to purchase the kind Bowie linked to. I just hope they fit better than my original ones.. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted May 18, 2015 Share Posted May 18, 2015 Not had a problem with fitment, I know Nige has used them in the past as well. It would be worth checking your manifold for flatness as well, if badly warped you are unlikely to get a proper seal no matter what gasket you use.... I got mine skimmed back flat, which I am sure all helps. You know they are warped if you try and get bolts in the end holes first and they won't go in/need drilling out!

elbekko Posted May 18, 2015 Share Posted May 18, 2015 It's strange, as far as I know we've always fitted the stamped kind, from a genuine bag, and never had any issues. Are you following the correct tightening sequence? Quote Link to comment Share on other sites More sharing options...
need4speed Posted May 21, 2015 Author Share Posted May 21, 2015 Ok. I'm really getting f in fed-up with this... Below is a pic of the bearmach gaskets. As you can see the fit is abysmal. Funny enough they are fitting EXACTLY the same as the previous type, ie protruding one side of the port and not close enough on the other... What next?

need4speed Posted May 21, 2015 Author Share Posted May 21, 2015 My patience has run out. I'm sick looking at them. The Dremel has come out. They now fit. Whether they will seal well is another matter but they certainly fit..... Quote Link to comment Share on other sites More sharing options...
elbekko Posted May 21, 2015 Share Posted May 21, 2015 Damn, that is indeed quite far out Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted May 21, 2015 Share Posted May 21, 2015 Wow, yes, a long long way out... Fingers crossed for you they seal Quote Link to comment Share on other sites More sharing options...
need4speed Posted May 21, 2015 Author Share Posted May 21, 2015 Yeah I hope so Bowie. It's still going to be a little while before I turn the key so if it fires up and sounds like a chuffing maraca I will probably have forgotten why lol What I did was rather than grind the "crush" area round the port, I elongated a couple of the holes where it bolts to the head. This allowed the whole gasket to move a bit to the left. Hopefully by doing that I've given it every chance to seal.. Quote Link to comment Share on other sites More sharing options...
DavidW Posted May 22, 2015 Share Posted May 22, 2015 The ones I got form Rimmer Bros with the fitting kit for my stainless exhaust seem quite good. The fit is fine and they are some sort of softish metal, almost like lead. Having only just fitted the engine into my chassis I unfortunately have no idea how they will perform.
