Timing Is Everything

Done a bit more since the last post. Cams are in, covers on, cambelt backing plate is on, cam wheels torqued up and belt is on.

Timing kit is on in this pic. Took awhile to time - wanted to get it spot on so I don't have to worry about the timing if it's not starting.


Going to be running 3 litre injectors. I've been looking for a place to get them cleaned, but there's noone near me that does it. Not even the Bosch place knew.

This is the injector pattern for the 3.0



This is the 2.5 - you can see that the 3 litre should give a better spread of fuel going into the cylinder - should make it burn a little more efficiently.


Thats it for now. I've started taking the engine out of the car. One head is off and the cams are out and going on ebay tonight - should make at least a hundred from them - maybe more.

Quaife ATB limited slip diff if in the box. Wasn't too much of a hassle. Can't wait to get the engine in a gearbox on now.

New Purchase

Just went to pick up a limited slip differential today.



Will fit it myself tomorrow (hopefully). Start on the car tomorrow too. Sump off and heads and maybe get it out of the car

Nice bit of kit.

Both heads on


Blanking plate (you can see the hylomar squeezed out if you look)

To Do List

Another day another head. Got the second head on yesterday and torqued it down. It's getting close to where I need the 2.5 to swap bits over.

Today I fitted the blanking plate and hylomared it into place. Torqued it to the same torque as the old plate, but I'm not sure if it's going to be enough. I'll give it a little more tomorrow - neither part is alloy (one mild steel and the other is the cast block), so it'll be fine.


MY TO-DO LIST:

Oil pump on - need to find out if the gasket is the correct one, as there seems to be a hole that in the block that is blanked off with the gasket, and a corresponding one in the pump.
Change Crank Oil Seal - a LOT easier this time as it's on the stand and i don't have to become a contortionist under the car.
Find which in inlet and which is outlet for oil - need this for the oil cooler
Water Bridge In Head - fit

Everything else i need from the other engine:
Sump
Remove heads
Get the inlet cams and put on exhaust of 3 litre
Engine out
swap - alternator, startet, dispack,cam covers, sump, pickup pipe, fit new power steering pump, ancilliary bits too

Fit the lsd that i'm going to part with 480 quid for. That should make things fun.

Rings and things

Here's the ring I broke. There's a lip on it, must have been half in and stick on the lip and my 'gentle' tapping took it off.


Close up of the ring.


South Wales pistons gave me a dodgy set to start - had two top rings and none of the middle one with the step. Had to go back, but the piston is in now.


Had a bit of spare time after putting new big end bolts on and torqueing them down
So I put the front head on and torqued it. It's tight - 25Nm+90degrees+90degrees+90degrees+15degrees. Me arms still hurting.

Oops

Well, the plate came yesterday so I fabricated up the piece, fits perfick. Hammerited it cos it's mild steel and will rust over time if not coated.


Started to put the piston in - AT LAST!! This is number 5 in - got them all in - was putting number 2 in and i split an effin ring!!! Bugger!! To pee'd off to take a pic, but take my word that I took a shaving off the lip of the ring.


Called the trusty South Wales Piston man and there's a set on the shelf - 11.47 plus vat. Go get it tomorrow and try not to chip this one. :(

Not much done today

Waiting for the steel plate so i can see if it seals properly before I put the heads on. Going to route a groove around the edge of the plate so some sealant will stay in there giving a better seal. Just in case.

Test fitted the adaptors into the oil inlet/outlets - no probs, but noticed a ridge inside the adaptors that might weaken the oil pressure. Drilled it out to be smooth all the way through.

Thats about it. Covered it with a plastic bag 'till I get the plate tomorrow. Says the weather is going to be peeing down until friday, so i'll be working on the 3 litre, not taking the 2.5 apart.

Block head

Was hoping to get the heads on today but missed a part - not my fault as i thought i had the raw materials to hand
Anyroadup - here's so far:


Here's a valve oil seal - you need one for every valve. They aren't hard to put on, but can be a bit of a bugger to get off, almost ruined a guide trying to pull them off until i found out to TWIST first. They get stuck on with either the heat making the rubber/whetever stick to the guides, or it's all the old oil coating them with a varnish and sticking them there. I'm for the second option - my dad (who worked on merlins and stuff) votes for one.



Here's how to put them on without damaging them
10mm socket. Easy.



2nd head half done - lifters are in on the inlet side



oh yes - thats what it says on the block.


cleaned the block up. Doesn't look that bad - was going to paint it with black hammerite, but I think it looks ok as is.


Top view of the block. That hole in the middle of the block is going to be plated off - it's where the original oil cooler went, but seeing as i've spent lots of money on rerouting it - it's not going back. This plate is what I'm waiting for to continue - i need to know if it's sealing before i put the heads on.


If you look on the picture above - on the top of the bores there is a bit that joins it to the block. Just to the right of that - thats where you find the cylinder sizes - from here you get you're appropriate sized rings.

Mine are 00 - standard sized.
