Hey Guest one of our sponsors Progressive Parts is running Black Friday and Cyber Monday offers - more details here
Red Cupra GT2871R
- Thread starter Jonny95 SXE
- Start date
Get yourself over to Surrey Rolling Road Jonny!!! Top roller
- heard reports that they're one of the most accurate in the country (well my country lol)
What I plan on doing is using bills as a benchmark in the UK and within a day or so do a RR at the irish "proving grounds" and then, if there is a difference I will be able to calculate how much varience there is.
Temps permitting etc.
it's such a lottery though

Hi all, going to stick 2 threads together now, since the mission was successful!
Hi all, Just an idea. I am taking loads of pics while rebuilding a spare engine I have. Is it worth while?
I got hold of a clean AYP (the original handwriting under the rear engine mount is still on the block allong with all of the white part number stamps and labels)
From here the plan was to strip the engine down completely,
hone the cylinder block
rebuild using new forged rods
use existing 20mm wrist pin mahle pistons (since it is one of few 20mm piston engine codes and have been known to handle 500+bhp)
new rings and piston seals
new big ends and crank bearings/seals
port/polish head
renew valve seals
reseat valves
skim head
reassemble
all while re finishing the exterior of the engine.
simple as.
so on night one project kitchen rebuild commenced
unload engine to kitchen and strip to the point just before oil falls out!
on night two.
was greeted by a house mate earlier wondering "what the f&ck is in the kitchen" so that went down well!
I didn't have the tool to remove the head to hand so I did what I could.
I removed:
oil filter housings
Timing belt and tensioner
rocker cover
Marked all cam retainers
Timing chain tensioner
Cams
Timing Chain
Seals removed from cams
All seals where in working order.
The head seems to have minimal wear with cam lobes perfect and hydraulic lifters perfect also
Is there any way which I could test the lifters?
and for progress,
everything has been re oiled now and stowed away wrapped in cling film.

Pistons are off rods now also will take pics.
Thats all for now.
the big cleaning operation is next and paint (boring)
Update for tonight parts are finally cleaning up a bit. Got the sump clean, oil filter housing, rocker cover and other pieces cleaned as well as a first pass on the head and pistons. I think I might have the final color scheme sorted also so looking forward to paint prep. all I need now is a valve spring compressor to strip the last of the engine,
where it all began
and ended
is this kind of wear acceptable?
quickly scrubbed
night 4 down...

Sorry for not getting more up on this all,
mad busy with workthese days so it is lacking slightly.
So for night 5. Tools arrived to remove all piston rings and valves. standard piston spreader and a motor bike valve spring compressor with a 21mm adapter for the intake valves. Took me ages to sort it out but finally got one on ebay for 30 quid.
right. so head on its side and lets begin
screw driver came in handy as did a magnetised screwdriver for collets and a agnetic pickup tool (impulse buy in aldi the night before)
intake valves out
placed into cardboard to maintain locations
spring compressor in action
exhaust valves out
nice shiny seats with no pithing or marks
intake tracks loverly and clean
exhaust, not so much
next job now is to "decoke" the head and have it skimmed. and also hone out the block. There is a 3 week lead time on rods at least I can have it all painted and ready by then.
nexy updatewill be monday night i'd say.

while removing the valves and pulling the stem seals I put a piece of acetake plastic into the bore for the followers just to make sure if you do slip it will minimise damage.
pics are crap but you can jst see it in the second valve from the left
Just for peace of mind really.

Neglecting this a bit recently,
so in the last few ive managed to paint the block, 4 layers of high temp 2 pack paint for the back (around the turbo area)
3 layers of black enamel for the front followed with a blue pearl and 4 layers of High temp fuel resistant clear coat.
I have converted one of the guys in the house here aswell!
so we have an engine builder in the making.
Got to work on lapping in the valves. Job finally done, a single course cut followed with a fine paste. The seats where pretty good to start with. there was a build up of carbon at the closest part of the exhaust valves on all cylinders. so a before (left) and after (right) shot.
and a finished inlet valve.
So from here Its off to get the head acid dipped and "de coked", skimmed and get the valves ultrasonically cleaned,
Ordering up a hone as I type ere so thats going to be next weeks work. All parts for the rebuild are finally being ordered on Monday.
What are peoples thoughts on polished mani's? I have one but am thinking about painting it...

wentmessing with the left overs of the blue peary too
so the rocker cover

next up is all the ancillaries.
