Delberts Wallet Posted September 14, 2005 Share Posted September 14, 2005 Planning on swapping the head on my K series (for one that has been ported and polished) and was wondering what bits and peices are needed. I've guessed at new HG and head bolts and coolant but what else? Link to comment Share on other sites More sharing options...
shn7 Posted September 15, 2005 Share Posted September 15, 2005 As there's a chance I'll need to replace my HG soon I'd be interested to know the answer to this too. Steve. Link to comment Share on other sites More sharing options...
Allen Payne Posted September 15, 2005 Share Posted September 15, 2005 Cam belt inlet manifold gasket (make sure it doesn't restrict the ports) Water rail gasket (the rear one above the starter) oil & filter. Link to comment Share on other sites More sharing options...
DohNut Posted September 15, 2005 Share Posted September 15, 2005 New cambelts etc, might be a good idea. And natrually some vernier pulleys to time the cams in properly Nick Link to comment Share on other sites More sharing options...

Myles Posted September 15, 2005 Share Posted September 15, 2005 And some cam shaft oil seals I'm *assuming* Delbert is going for a fully-built head - or at least, I hope so... He might want to take advantage of a 52mm TB while he's at it (I have *just* the thing... ) - but my fettled VVC-plenum (also force ale) is possibly a step too far... Project Scope-Creep is live...

GTD Posted September 15, 2005 Share Posted September 15, 2005 Novice I'd recognise that white Armani number anywhere! Delbert - when you find the answer we can do a bulk buy (well, two of us ) G for Geoff Link to comment Share on other sites More sharing options...
Delbert Posted September 15, 2005 Share Posted September 15, 2005 Its frightening how somebody can read my mind and has decided to empty my wallet....... Think I best speak to the area comandant about his plans to sponser me 😬 And the Very nears and Zost are as far as I can go IF I am to compete (well how we all larffed at that word) How I can dominate the bottom of the table in Goup 2 or 3 next season.. So its Sprints or staight to 200bhp simple choice really!!! The Liver is an evil organ and deserves to be punished Link to comment Share on other sites More sharing options...
Mick Day Posted September 15, 2005 Share Posted September 15, 2005 When the cambelt's off best to replace the water pump at the same time. Also budget for new stretch bolts as well Link to comment Share on other sites More sharing options...
Delbert Posted September 15, 2005 Share Posted September 15, 2005 Give us you're best sales pitch then Myles ... Why would I want a 52mm Botty Throbby anyway and is yours at a bargin price 😬 (you know ,, in the we sweated shoulder to shoulder threw 2 campaigns of buggers at Blue light sorta cheap 😬 😬) The Liver is an evil organ and deserves to be punished Link to comment Share on other sites More sharing options...
Myles Posted September 15, 2005 Share Posted September 15, 2005 YWHM off list. I'll bring it along anyway - it's a 5-10min job to swap, so you could try it and see... I've heard that: Hmm - well I ran it only briefly just before we put the PSC in. I came to the conclusion it was worth the money - especially as the MEMS is perfectly happy with it. I've probably written all of this up under the PSC section on my site somewhere, but basically... As you probably know, the tb consists of a disc on a spindle - bit like a lollipop. i.e. the butterfly... The std. 48mm tb (ali or placky body) has a plastic butterfly (so quite thick) whereas the 52mm has a metal one (thinner). The 48mm version also has a wedge bolted to one half of one side of the butterfly (think of it as a chunk of chocolate-orange laid onto a choccy digestive... ...shades of Happy Air coming in here...) Anyway, the wedge is designed to limit the airflow at very-small throttle openings - and to limit it progressively (to avoid jerkiness) - but of course it gets in the way at wide open throttle (WOT) - a choccy digestive with a choccy-orange segment on is not as thin as the digestive on its own. ...and neither is as thin as a large Rich Tea - which is what you are getting with the 52mm tb, IYSWIM... Sooo, the Rich Tea lets in much more air at WOT (bigger diameter, thinner biscuit, no wedge) and also lets much more air in earlier on (at low throttle openings) - so feels much snappier in response. Various MG/Rover fan sites will claim excessive hp gains for the tb - it does make a difference to the oomph in qualitative terms (about the same as changing from a std. exhaust to a comp version - I felt - but well worth it in VFM terms). It also seemed to add an extra chunk of induction noise - and I quite liked the extra whoosh as you whacked open the throttle... Project Scope-Creep is live...

Delberts Wallet Posted September 15, 2005 Author Share Posted September 15, 2005 The head is fully built but currently has "NEW" piper 285H cams installed so I plan to take these out and replace them with my Supersport ones (running on Plenum and MEMS ecu you see) Cam belt isn't that old so I plan to re-use that along with the Verniers that were also fitted at the same time. As the Cam seals are as old as the Cams ie new I'll re-use them too? So list is; Head Gasket Inlet Gasket Zorst Gasket (may re-use though) Stretch bolts Water Rail Gasket Coolant Oil + Filter Anyone want to buy some Piper 285H cams for an EU3 Jengin?

Englishmaninwales Posted September 15, 2005 Share Posted September 15, 2005 check the 2 water rail to head bolts are not too long and bottoming out when tightened. Caused a leak on mine and a common problem according to DVA. And cam carrier sealant (GGC108) Link to comment Share on other sites More sharing options...

PAUL MARRIOTT Posted September 16, 2005 Share Posted September 16, 2005 -Valve stem seals -Foam pad, if you have an Appolo -What about new set of cams to take advantage of the porting. -You should be able to re-use the stretch bolts. I've reused mine twice - they where showing no signs of distortion. -Compound to polish up your exhaust while you have it off. -Cam seals. -loc tight Paul M.

Myles Posted September 16, 2005 Share Posted September 16, 2005 I would hope that the valve stem seals are fine as the head would otherwise be good-to-go as purchased. My apollo installation doesn't use a foam pad in the camcover (it does have the standard metal version on the cam-cover breather though - but this doesn't need renewal in general). The 285h cams that come with the head would be great - I use an equivalent cam on my PSC engine - but delbert is restricted (at the moment) to running on MEMS and on a plenum (not even a VVC version - although I've got one to sell to him if he needs it... ) I bought new stretch-bolts for PSC (£60ish a set) but reused them on the subsequent 2/3 strip-downs and rebuilds 😳 His exhaust is brand-new...

PAUL MARRIOTT Posted September 16, 2005 Share Posted September 16, 2005 I've also got a VVC plenum, lightened and painted a nice fiery red that I could sell D, Only problem I had with the VVC Plenum and 285 cams was that the car drove like a pig at anything under 3000RPM.

Myles Posted September 16, 2005 Share Posted September 16, 2005 Paul - there were a stack of problems with the engine at the time I tried it (unsuitable map and agressive cam-timing for starters) - but PSC was undriveable on the VVC and 285s - particularly in carparks...
