Lancia Delta 1.6 HF Turbo ie hillclimb...
Posted: April 9th, 2012, 11:05 pm
I thought it was about time i posted something about the hillclimb car i'm building. I have LOADS of project photos on another forum which would take hours to downsize and upload here, so i thought i'd just post photos of the engine build. As much as i'd have loved to, I won't be spending the money on race rods and pistons but I will none the less try and build it to a high a standard as practicable.
So here is the starting point, a 1.6 turbo i.e. block stripped of its ancillaries and head removed-
No fancy wash machines here, just a Jizer spray bottle, a couple of old tooth brushes and tentative but surprisingly willing assistant (the missus!). A bit of elbow grease later and we're getting there-
I always like to keep it covered up-
With all the ancillaries kept in one place-
My lovely assistant on the case again (at the cost of me buying dinner out!) removing the oil pump-
The engine turned over and ready to remove the mains caps. I didn't realise how tight these were, even with my weight balanced on top and the missus swinging on the breaker bar we were still just spinning on the work-mate-
Time to get the gun out, cue comedy bond-girl pose!-
With the core plugs removed I gave the water galleries a brush and blast, then poured a couple of kettles of boiling water over it and sat the block in front of the space heater to make sure it dried properly-
Then it got a session from the brush drill/grinder before hammerite red oxide primer and two layers of top coat-
Now its time to hone those bores. Bit of a step at the top, the engine has done about 75k but for this project i can live with it-
The rods/pistons removed and ready for splitting and cleaning-
Now on to balancing the rods. I started by making a stand with a bearing'd swing arm to hold the small end and then made an L shaped stand with 2 small bearings which holds the big end and sits on the scale. Then it was a case of linishing the caps to match the big end weights to the lightest one, then weighing the whole rod on the scale and matching the weights by removing metal from the small end-
Onto the head - I never did seem to get that pesky exhaust cam thrust plate to stop leaking, so it was time for drastic action. They are designed for a specific thickness of gasket (about 25 thou if i remember correctly) which are getting hard to get hold of, i finished off Tanc Barratts stock a couple of years ago. If you use no gasket or too thin a gasket like I did a couple of years ago (almost had valve/piston contact!) you can lock or at least restrict the cam from rotating-
So I turned down a thrust face (23 thou deep) and i'm going to use a liquid sealant. I've trial fitted it with no sealant and its given 7 thou end float, Guy recommends 3 to 9 thou so even if sealant spaces me out another 1 thou i can live with that-
More coming soon.
