This weekend I finished off some stuff on a mates 21, polybushed the wishbones on my XC90 and found myself with time to spare...so I welded up the front crossmember where it had perforated and started cleaning it up a bit.
Decided with the awkward shaping I might try blasting it with my...
I know I want to get it back together, but i've just taken on too much other stuff. My own fault. Hope to see some decent progress soon, especially over the xmas break. I wanted it running this year but I might not quite make it.
Quiet lately! Been tinkering elsewhere and busy with other stuff :) (Sold the 250, bought a 220, Changed the engine on a 0.9 TCe Mk4, Fixed a Mk3 Clio 1.6 Initiale, finished a 21 Turbo engine rebuild, sold another MK4 Clio 1.2 and and and...)
Still, I threw some seam sealer around
Messed...
They're passable when cold, but really get on song when hot & pushing hard. I could really feel them tighten up and start to bite as the heat came in on track.
New gearbox mount arrived so took the leg off and cleaned it up. It was missed from blasting for some reason.
Took the others off too and lobbed some paint around
Checked the new wishbones & bolts fit, wishbones complete with bushes and balljoints for under forty quid off Autodoc for both...
It's not too bad as you have plenty of cars in the paddock to look at and plenty of people to talk to. It's very friendly and i've had some great convo's with people about my car and/or their cars.
You should expect a minimum of 3 runs unless there's a big crash or oil drop, every time I have been I have had three, a couple of times I turned down a fourth too. It's about a minute per run, it's REALLY steep and be really careful under the trees especially if its wet/damp.
Turned my attention to the fuel tank - these are old skool metal tanks not polymer so although I protected the outside I thought it'd be wise to do the inside too. Got some Fertan 2 part stuff.
Before
Made up a stirrer for my cordless, as I couldnt be arsed with the extended stirring out...
Exhaust manifold sorted and bolted up :) thanks to sparkie and Clarkey for helping out with that!
I managed to get the lump off the bench, bolted a few more things back on and chucked it on the subframe. Needs a new gearbox mount so thats ordered along with steering rack gaiters, then some fuel...
Fitted a temp sensor in the head end plate, stuck the clutch and flywheel on...
Removed a broken exhaust stud i'd forgot about
Found the old exhaust manifold wont fit with the new EFI inlet, so have sourced an R5 GTT one to use with it. They're different to the early R9 ones.
Bunged...
Head resurfaced and valves lapped in
Bunged it on along with the bucket tappets, pushrods and rocker shaft, took me a few mins of puzzlement to figure out why the rocker shaft wouldnt go on but there is a cutout on the shaft that sits on the side of the studs/bolts. Didn't realise that (well...
Welded the belt pulley to the keyed crank drive
Set it to TDC, aligned the 36-1 at 90° after TDC and welded that on too. Not very good welds, don't think I had the power high enough. Might redo it at some point!
Cleaned up the flywheel, and dug out the clutch I bought for it - I purchased...
Gearbox is back from it's strip and rebuild. All new bearings and seals, tarted up, looking sweet! My end casing was rusted through, luckily I had a spare R19TD box with a good one so that got pinched :)
I took it apart again, cleaned everything AGAIN and examined the shells closely - what I had neglected to do before it seems was look closely at the back of the shell and I found a splodge of something on the back of one of the shells. Maybe a squshed bit of oily cardboard or something? I dunno...
I've taken ID measurements with a mic, it's round as far as I can tell to the nearest 0.1mm, I think I need someone with more accurate kit to have a look at it...
The big end cap & rod have locators for tabs on the bearing shells. These tabs must be on the same side/faced together.
If I keep all the tabs on the same side of the engine then this one cap faces the other way up to the rest. If I put it so the cap orients the same as the rest, the side...
It's not, they are usually all the same way around. Thats why it seems odd to me.
No, I was measuring with a micrometer
Absolutely 100% it's the original part
Small end is fine, checked that.
Checked that too, it's normal. It's defo the big end as it turns fine when the big end is finger...
Got some replacement studs and swapped in a pair of old big end shells. Still the same issue. WTF.
Took it back out again, took the shells out, gave the cap and rod a super hard clean/polish with a dremel and fine wet & dry, fitted the new shells again and reassembled. This time I can turn it...
Indeed. The fact i've bothered to buy all new kit makes it even more frustrating. I've got new studs on the way, all I can think to try now is swap the shells for the old ones, if it turns smooth after that then it must be the new bearings out of spec!
Gearbox is back, completely rebuilt, new bearings and seals, vapour blasted etc. Hefty price tag though, £450 :eek:
Decided to reassemble the engine now the bearing shell shenanigans you may recall from xmas were resolved. Or so I thought. I fitted the pistons/rods and did up the big ends...
So - engine bay - what do I do?
Clean it up, 2pk prime & paint
Clean it up, gravitex, 2pk prime & paint
...do I laquer it?
When I say clean it up, obv I need to remove loose paint and rust but what sore of prep do I need to do for the primer?
I've only ever sprayed my (new) roll cage in...
I managed to get the welding done Saturday and also the majority of the underside clean up and BHH80 done too before I knocked off about half 8, I was knackered! Sunday this meant (after cleaning the Grand Modus I am about to sell) I could get the Bonda primer on, then get ready to Gravitex the...
