I'm currently in the process of doing a bit on work on the old golfy, which has required taking the engine out. Now i'm not going soft but i'm thinking about removing the bugpack side engine mount inserts i've got and just using standard side mounts with a poly front stubber and rear gearbox mount. It's just to try and reduce a bit of the vibration i get, not for comfort reasons you understand, just fed up with every single nut and bolt vibrating loose and keeping loctite in business! Just a bit worried about cracking more manifolds what does everybody else use???
I changed my side mounts back to standard and the rear one to a diesel one and it meant I could actually see the speedo when idling the front one I left as a poly one (partly due to the fact that I couldnt get the bugger off) it keeps the engine from moving around too much. Not cracked a manifold yet (5K of stupid antics)
ive always used the poly front and rear g/box with no probs,the s/sprint manifold held up fine too. i replaced the side ones with new vw ones. neil.
I fitted a flexipipe aft of the normal ashley 4-branch and never had any problems with cracking (road + track). Also I fitted exhaust bolts & 'springs' (see Pug 205 I believe) on the 4-branch-to-front pipe flange. Having said that I was running polys all round. Still, can't be a bad thing just to allow as much movement in the pipe as poss without it leaking.
Where abouts can you put the flexpipe Chris? This is how my Ashley one is: The 2.25" part is what comes with the manifold and I need to find something or someone to step this down to go into a 2" system. What sizes are the flexpipes? Sorry Ian.
Jetex sell stepper pipes for about a tenner, thats what i used to step my ashley from 2.25" upto 2.5", but they do other sizes too, have a look at the demon thieves catalogue, then go direct to jetex to buy it!
No probs - I was where you are now not so long ago. Flexipipe goes to the right of the flange in your diagram but before the centre section. I think I used about 25 - 30 cm including pipe overlap to give plenty of flex. My fitment involved using a Jetex 2.5 inch system, but I found I could get flexipipe between the 4 branch & the Jetex without cutting it. So I was stepping up slighly (just because Jetex was 2.5 inch) but you need a stepped sleeve from Jetex to get to 2". Quick look at the Jetex site and I think I see one that suits your 2": Clicky They post, but Merlin Motorsport at Castle Combe have them on the shelf with you're passing. Careful with ID & OD measurements BTW. If this doesn't work, there are some Volvo tailpipe stepped sleeves which, much as it shames me , will be of use. Part nos can be dug out if you need 'em. Flexipipe from sourced from a Bosal-supplier, called Silencer distributors. A welder/brazer is a handy option for joining flexipipe to pipe, although I managed with exhaust clamps & paste originally and it was fine, if a little untidy.
Those jetex stepped sleeves only allow you to go from a 2" into a 2" judging by the dimensions, when I was looking around last week I couldn't find one that goes from a 2.25" down into a 2". The OD of the pipe that goes into the 2" part needs to be a touch less than the ID of the system. I've got a diagram somewhere showing what I mean but I haven't seen what I need on t'web unless Jetex have more sizes which aren't on there site?
I ended up sleeving a Volvo stepped sleeve into a Jetex one. These offer other combinations than Jetex. They are the tail pieces off the 440 hatch which extend out of the rear silencer to the bumperline (means they can get away with the same silencer piece for the 440 / 460 + varying length extender pieces. The local motor factors should have details. I used the 440 turbo piece, but the less powerful models were a smaller diameter. Could be your answer. Takes time this one - really frustrating which is why I remember it all!
Cheers Chris, I'll have another look tonight when I'm in from work the fueling from carb to injection has taken me a few weeks to sort out, now this! Hopefully it is a little more straight forward if I can find the parts easily.
This is the reducer I need (shown in white): Is this how the Volvo 440 part is? Or as you've just mentioned above, you've sleeved this onto the stepper sleeve, as in the Volvo part is the same size as the 'from manifold' pipe with a sleeve clamped over the top, like how Mk4 Golf exhaust systems are put together? Any chance of digging out the part number of the Volvo pipe if it fits in with my diagram please Chris? What was the ID of the flexpipe you used, 57mm? What sort of prices are we talking for both? Thank You.
powerflow? i bought a piece for a tenner to join the s/sprint manifold to the magnex system,no flexipipe but suppose they could have supplied me with it. neil.
I have a poly front, standard rear (gearbox), standard nearside (gearbox) and diesel offside. Supersprint manifold with the usual flexijoint that comes with it. Very little engine movement, no probs with cracking manifolds and no more vibration in the cabin that as standard. I did try a poly rear (gearbox) mount but the difference in the car was huge - so I sold it to Neil (riley), who seems less concerned about vibrations than I was!
can i have a breif hijak....... i have a TSR manifold which is the same as the ashley one (or so i'm told) what do you use to join the 4 branch collector to the 2.25" pipe?? it seems to me that if bolted it wouldn't make a very tight seal, is there a collar that will fit around the inside of the pipe to make a snug fit to the collector??? Thanks Ro
You should have an olive to fit in between the pipes? Then using the three bolt holes, get some long bolts washers and what look like valve springs (see Pug 205 exhuaust + others). You put the bolt thru the flange, then the spring on the other side, then washer then nut. Wind up until snug + a bit, but do not allow spring to go coil bound. This allows some movement in the assembly on acceleration/gear changes etc Does this answer?
Is an olive some sort of sealing washer? metal? I didn't get one of these with my Ashley! Are the olives and springs easy to come by? Any part numbers and/or likely suppliers? Oh and does that Volvo part fit in with my diagram? If so, could you dig out the part number for me with a rough price? Cheers.
The olive should be sitting on a metal flange at the base of the 4-branch. Should be removable with a twist. Did you buy the Ashley new? Should have it.. I believe it is a Citroen part, if not. Go and bother the Kwik Fit boys if you don't have it. Springs? Again, if in a hurry, pop round to Kwik Fit, pick their brains, and you should get an answer on what you need. Slip them a fiver and you'll get the bits . Otherwise scrapyard time. I saw some springs like them on the manifold of a Mk5 Escort a few weeks ago also. [Ashley is the same as TSR, BTW] Volvo part nos I will dig out this eve . Should be a fiver or thereabouts - dont' buy from Volvo, go to a factors.
Yep, you should have got the bits with the ashley manifold, but now you mention it i didn't get them either, i think i chased up Rally design who ordered some in for me, still charged me for them though i think.
Cheers. Definately haven't got one of those olives. From this picture, my top diagram shows a straight section coming off the collector after the flange but there is a flared end on the adjoining pipe that goes onto the system. Will an olive still work?
