    Default Renault Fuego Turbo Head install

    I am rebuilding my 1983 1565cc A5L turbo motor for my R10 and I am curious what standard practice is for installing the head. I have a haynes manual(I know, really not the best source) that calls for a special install tool, but I cant quite parse what it should look like. My concern is the distributor alignment mainly, as nothing really seams to constrain the head but one alignment pin.

    For aligning heads try cutting the heads of some old head bolts and then cutting a screwdriver slot in the top.
    These bolts can be loosely fitted to block when fitting and aligning the head and then unscrewed when the head is in position and a couple of head bolts on on.
    Yes, one locating pins seem a bit inadequate although it probably is fine in the factory.

    Cheers RTT

    Yes the head will pivot on the central sleeve. The fitting kit is basically a couple of pins that screw into the head bolt holes. You could cut the heads off a couple of old head bolts to achieve similar. You can line up the head once on the central sleeve by making the head casting line up with the block in various places. It all becomes apparent when you put the head on.

    More pressing, so to speak is the liner protrusion.

    I have a factory manual for your engine your email address and i will scan the appropriate pages and email them to you.

    I have also made up a copy of the factory tools before I was lucky enough to come across a set from the factory. Mine were made as described above and a 4mm spring ball added to hold the head gasket in place while lowering the head onto the gasket.

    Head gasket alignment & head alignment is very important to make sure everything seals up properly.

    Thanks for that. I did not pull the liners, mainly because the bores still look great and the liners arent leaking. I figured Id let a sleeping dog lay. If you think I ought to pull the liners for any other reason, let me know. Do you think their position might have been disturbed since the head removal? I'll set up my depth gauge to see were they are sitting.

    As long as you have not turned over the motor with the head removed the seals should be fine.

    I would be holding down the liners with washers and bolts so the liners can't be dislodged.

    I would still check the liner protrusion, as this is critical if you don't want blow a head gasket.

    G'day again....

    that's an oops in'it....

    A5L, used in others ?

    OK, so I found an Autodata manual here for r18 & Fuego [used to be online as "Autodata-Renault18.pdf"] I could put this in dropbox if you need it, A5L gets a mention.

    cheers,
    Bob

    Its also important how the head was removed - if it was levered up the liners may be dislodged. Wet liner engines need the head gasket seal broken by dislodging the head laterally (ie whack it with a soft hammer sideways).

    Default Head alignment matters reported to me

    Slightly beyond my experience, but I'm told that you also need the correct tool to align the distributor drive with respect to the correctly positioned cylinder head. It is MOT.412-01 - for the 16TS engine. Otherwise, I'm told, you run a risk of destroying the distributor drive eventually.

    I've been sent two photos which label that distributor drive alignment tool as #2. Tool #1 in the photo is the head alignment studs with #3 being the left-hand threaded extractors that are used to remove the studs after the head is fixed in place and the gasket can't move.

    It's important to have head gasket exactly in place also with respect to the rubber gasket ends that mate up and prevent oil leaks from the camshaft gallery.

    Not a trivial job unless you are doing it all the time I guess...

    While typing this the third photo arrived, showing the correct alignment tools on the left hand side. On the right are the same set but for the 16TL engine (non-crossflow of course).

    Good luck.

    Default Head alignment

    Diagram of alignment tools in place... I'd always wondered what that extension to the block face was!

    I actually made one of those, very easy to do on the lathe out of a bit of 16mm round bar; 16mm x 3mm flat bar and a 3mm roll pin

    The actual tools have a small spring loaded ball to hold gasket in place while positioning head

    I love the service tools - so well thought through! That illustration, btw, is for a 16TL head, not a 16TS head.
