Finished a head gasket repair on a friends 1.4 Turbo Zaf C.

Wife has one of these (2016 SE 1.4 Auto) - I really should dump the coolant on this. Been giving it annual oil changes with Dex1 Gen2.

It does low miles, but lots of stop/start town stuff.

It's been very reliable so far, just changed the coolant hose that goes from the coolant tank and plumbs in what I assume is the main coolant engine feed. The one with the metal clip, it was starting to weep a bit.

It blew a windscreen washer pump around 2 years ago.

But apart from that since 2019 been a solid mummy wagon.

I guess that is the smaller vent hose from the top of coolant elbow at the gearbox end of the engine to the header tank?

The hose end goes brittle and fractures, the part with the metal clip is actually (and rather crazy!) an adaptor with an O ring on it (easy to swap the O-ring), the main hose has a plastic clip integrated into the end

Changing the oil+filter is interesting,  if car isn't high enough you can't drop undertray flap down enough,  .....

you need a Pela oil-sucker-outerer  :y

 I'm of the old skool,, undo sump plug, and make a mess on the floor as the tray is positioned wrong,

I've a Pela because one of my Smarts doesn't have a sump drain plug, but I do remember having a car where the under tray fouled the floor before it came off.

I have the same for the F-type, it actually has a metal tube inside the oil filler which passes down to the base of the sump by the drain hole to suck the oil through:



It is by far the easiest car I have ever changed oil and filter on  :o

Yes springs will be worn. Yes I think the OEM shocks are sachs.

The negative camber is just one side so something bent or damaged on drivers side I suspect.

Measure the ride height both sides, I bet the drivers side is lower

There is pretty much nothing you can bend which will impact camber and not toe  :y

Primary height setting on those is the springs, as the car ages the springs weaken, the suspension sags a bit, the static position of the wishbone sits a little higher and you get a bit more negative camber.

Just changing the shocks will yield poor results, springs are the primary  :y

I suspect the standard Golf shocks ae ZF (so Sachs/Boge) and the WSS setup would be Monroe

That points towards an issue either with the cluster or the connection from the engine ECU.

The dash is the one major difference between the Catera and Omega, and without seeing behind the cluster there may be additional wiring/plugs for the extra displays/warnings.

I suspect that the alternator only feeds the charge light (and battery voltage gauge), whereas the rpm signal comes from the engine ECU information (crank and/or cam sensor).

If the pedal trick works*, any codes may highlight a discrepancy.

* It should as the car is DBW.

The speedometer issue is almost guaranteed to be unrelated.
But engine right on high rpm. Car starts to stall when accelerating. Maybe I should start with (crank and/or cam sensor)?
Previous owner said that they changed crank sensor from omega.

Fuel filter ok?

if it miss fires on acceleration that points to ignition voltage and coil packs

(head gasket on these is done without removing the chain assembly and timing cover).

I really can't picture how this is done.  :-\

How do you remove the head and cams without taking the cam sprockets with it?

Cam sprockets are unbolted and have the chain on, tension is removed from the tensioner and the sprockets sit in a casting on the timing cover, head slides out and up (having disconnected the inlet, exhaust, water outlet, a few water pumps bolts, and some timing cover bolts.



On re-fit, crank t 90degrees before TDC (all pistons to the half way), head on, set the cams and lock them, bring the pistons to TDC and and lock the crank. Cam sprockets bolted on, tensioner released and tighten the bolts.  :y

On my India trips recently we have indeed been traveling across Iraq and hanging a left before Ukraine when heading to/from Dubai   :-\

Finished a head gasket repair on a friends 1.4 Turbo Zaf C.

Been a pig of a job, mainly thanks to the moron garage that has been taking cash for previous work and servicing.

Head skimmed as it had been cooked and warped, broken coolant hose replaced (it had been wrapped in self amalgamating tape), repaired the vac connection from the manifold to the brake servo which had been snapped off and plugged with a bolt, replaced the missing two bolts on the water pump,  fitted a new stat as they had gutted it so no internals (how the hell did they think that would help!).

Got it running and it shat its oil load all over the road as the turbo oil feed pipe fractured due to being distorted/bent and rubbing on the manifold, the chain tensioner also decided it had had enough (head gasket on these is done without removing the chain assembly and timing cover).

I have not seen black death in a cylinder head like this since the days of the crappy Ford CVH lumps, two hours cleaning and a couple of trips through the dish washer (bottom end was not as bad as I dropped the sump to check big ends and the pickup gauze) to get it up to scratch

You could always look to find somebody good with a soldering iron, the failure mode on the ABS module is a fractured bond wire, in fact two, (as there are two in parallel to increase current handling), not to hard to repair but it is fiddly.

This one is midnight blue with tan leather, I'm going to keep the colour the same but although the seats look in good nick I know of someone local who can refurb them completely, I'm going to keep them the same colour but will have the leather in the "diamond quilted" pattern that can be seen on most Bentleys.
Keep them original, Mick.

^This!^  :y

How original though?

Say, for example, you replace points and coil on a sixties classic for electronic ignition. Or modern tyres and brakes.

What Rangie describes sounds like an 'acceptable update' to me.


Just wanted a slight difference to make it more "personalised" to me, everything else exactly to as new condition, even my missus liked driving the Granadas at one point we had two she had a 3.0 GL & I had the 3.0 Ghia, the MK2 I had was only a 2.3LX in gay gold 👍

You go for it, its your car, purchased by you, for you, do to it what you want.  :y

Does it sound like a hovercraft for many minutes after you lock it and walk away?

Not a fan of that engine!
  >:D


Yeah, about 20 minutes. I thought I had broken it. ;D

Bit of a shite design to get around packaging constraints, turbos in the V, they have 'thermal challenges', we use the same lumps in the new RR and RRS, not nearly as good as the previous SC 5.0 we had.

We have been looking at how we integrate LEO solutions into a car for some years now, have worked directly with Amazon and Starlink on this.

So have you set it up, tried it, and its not performing?

Basically yes.

No obstructions as it looks out over fields. Starlink customer service say that it's as good as it is going to get.

Now using Lebara with the Vodaphone network through a Huawei router,  which costs 12.50 a month instead of 75 for Starlink.

Connecting the TV aerial to the router seems to have made it much faster.....or is that just the placebo effect.

Possible but far from ideal, you can get directional and external cellular antennas which are MUCH better, they just need pointing at the cellular mast (for directional)

I shall look into this. :y

Do you have one (or more) you can recommend that works well and won't break the bank?

If you can get the modem as close to the antenna as possible then I suspect most will work ok, check as you might need two antennas (to get 2x2 MIMO) or even 4 if its 5g, will depend how many antennas the box has today.

I just use car shark fins as I have them lying around  ;D
