    Reached a small milestone last week. Finnished cleaning and checking my crank, conrods, cylinderblock and engine Block With flywheel, pressure plate and crankwheel. Brougth the parts to the engine shop for a rebore, cylinder block decking and balancing of the Whole line With New pistons.

    Here is pic showing how I machined dowels/oil corrector With O-rings between the cyinder Block and engine Block. I will not use gasket, only Loctite Flange sealer.

    Re: Fulvia 1,3 HF

    This is a very interesting thread on your engine build.

    Some queries,

    What CPS pistons are you using and what compression ratio are you aiming for? Why choose CPS?

    Are you not going to use any cylinder head gasket at all?

    Have you decided on valve sizes and camshafts?

    What lubrication system do you propose, oil pump, sump and baffles?

    It's a very informative and detailed thread for which we are grateful.

    Keep up the good work!

    Ultimately what you need is what we use on race cars;

Some holes have helicoil down in the bottom and some holes have threads in the top that looks like time serts (they looks ok). Other holes seem to have the size I describe under, bigger outer diameter. They also look ok.

    I bougth a set With time sert on Ebay, only to find out that there was not enough material left in the holes to use them.
    Time sert looks very strong, unfortanetly they need tapping With M10X1,25.

    I need threads something Close to 12,0 mm. (I dont want to foul the dowels for the caps)
    Found some inserts in stainless steel With M8x1,25 inside and M12x1,5 outside. I think Outer diameter of threads are 11,8 mm or something.

    You mentioned big serts, is it what I am lookig for?

    Thanx Langap

    My CPS pistons will give CR around 11:1 (based on deckheigth), Maximum 11,2:1. They are light design and have generous valve Pockets for full race cams. This pistons are well known and used by many tuners for years. I also looked at Omicrons pistons, great pistons but did not give me my desired CR.
    I will use 1,2 mm. thick headgasket, The pic in my last post showing the dowel/oil restrictor is machined at the underside of the cylinder Block.
    My 1,3 HF engine have 1600 sized valves from the factory, 34 mm. exhaust and 38 mm. inlet. It is not Space for bigger valves without reducing the 14mm. plug to a much smaller plug. Since my 818.342 exhaust cam was badly worn, I bougth New cams from Italy.
    This cams have more duration and a bit more lift than my 818.342 cams, so I want to raise CR to retain some midrange.
    I am not aware of the problems With oil surge, but I have to look into it obveously. My oil pump is machined to a end clearance of 0,02 mm. When measuring the rotor tip clearance, do it from the back side trough the oil passages With the cower and screws tigth. If not you will have a fase (to big) Reading With cower of because the rotor tilt.

    Cheers
