Smoother than silky the silkworm's favourite silk pyjamas...

:pimp2:

Over a very nice weekend at Kierancorp towers, we have made the world's smoothest 4 pot out of an old galant...

It was the usual story.... Amsoil Power Foam (coughcoughsplutterfartpopsplutterVROOMcoughcoughc ough) and a new air filter.

Then the oil.... Amsoil engine flush added to amsoil engine oil, run around for a good 15 minutes, drain, new filter, Comma flushing oil, run around for 10 minutes, drain, new amsoil filter, fill with Amsoil 5W30 (a better choice for winter I thought).

And then the plugs. The old plugs had been in for 15000 miles (standard platinum NGK BKR6E), but I'd suspected that there was something up with them for a while. When we removed the plug from cylinder 3, there was the problem. The other three cylinders had the expected gap at 1-1.1mm or so, but cylinder 3 had only 0.6-0.7mm, so the spark would be weak.

And now it is oh so very smooth, no start-up ticking and just wants to GO. Loving it!

So thanks to K, thanks to Alex (for many cups of tea, bacon sarnies, good conversation, etc) and thanks to Don!

I kid you not peeps when I say that the GLS flavour of the 4G63 is a wonderfully smooth unit when it's a looked after one (as Isaacs most certainly is). It really knocks spots off most other 4-bangers you care to name. In fact, I'd say the GLS unit is easily smoother than the VR-4 engine, despite the extra two cylinders - Mind you, I've always felt that the Twin Turbo V6 is a rather 'gruff' unit - especially against the v6-24.

Reminds me how smooth my GLS was.... If only I knew about Amsoil back then!:thinking:

I certainly think so.... the petrol 4s that I've driven in order of smoothness:

1) GLS 4G63
2) Nissan Primera 2.0? (current blobby ugly shape)
3) Audi A4 1.8 (old shape, X-reg)
4) Toyota Avensis 1.8 VVTi (current shape)
5) Vauxhall Zafira 2.2i (sounded like a diesel just above idle!)

The 1.8 VVTi is surprisingly gruff, but awesomely efficient (auto, it got 37mpg average on a motorway run to hull... An auto passat TDI got 38 on exactly the same run!). The vauxhall was the usual vauxhall ****e... overly heavy flywheel, rough and gutless. Primera was a nice drive, but ugly as sin inside and out, and that natty reversing camera is only there because you can't see **** out the back. Also, you can't turn off the computer/satnav screen, so it glows annoyingly at night.

But I still love my 4G63! If it had the efficiency of the VVTi who would need a diesel?!

those new primera's sure as hell are ugly. I laugh openly at people on the road driving them.

The 6a13 is a smooth engine though, I like them so much I have 3 of them :)
