3 years 4 me.

I haven't got a single V8, and never plan to either. There is something about them I don't like, sound of them I guess and the size I find too big for any conversion that interests me.

I mostly have 3800s and had a few aircooled VWs in my time, worked on heaps of ford 4L(hate those) and number of 202s as well, 202 is a great engine.

My fav engine are actually flat 6, like Porsche and suby EZ series engines. Get a hard one every time I hear the sound of a flat 6.

different strokes... ive owned 4cyls, a 5 liter, a ecotec v6, alloytec v6 and an ls1 and the ls1 is by far my favourite. just whack on a pair of headers, cats and exhaust and fiddle with the tune and its a powerhouse, not to mention being able to get 9.8L/100 on the highway.

my least favourite motor at the moment is the alloytec. triple timing chain quad over head cam getting too complicated. already spent $1200 on the timing chain!

On a Ford six forum I got told I was terminally stupid for asking about inlet valve stem lubrication in a boosted engine because the positive pressure would force the oil away instead of sucking it down the stem as normal. They just didn't get it.

If you want to read really low grade tech advice go to the MSD forum.

LOL, those bloody timing chains. I think GM tried to cheap out and changed the chains. Those engines seems to have the trouble, the other alloytec's with the other chains seem to be ok from what I hear. Was yours the 7mm pitch chain?

Funny thing you mentioned fuel economy. Many years ago I took my VN V6 away for a long weekend. Was a fairly long trip and at the end of it all it had averaged about 10L/100km, however on the return trip I left Rotorua and pulled of the motorway in Manurewa 2 hours later. Any kiwi should be able to tell you that is generally a 3 hour + trip The old VN wasn't to bad on fuel, even with a full load. One day I actually drove it nicely and it averaged 6.9L/100km

If I had to have a V8, it would be LS1. they are very similar feature that ecotec have, but better. They are light as too!


EZ36 conversion in my VW would be sweet as! 260Hp, 335Nm NA out of the box. bit better than 60 odd HP lol. AVCS and VVL, integrated oil cooler, COPs
Very compact (same exterior dimensions as EJ flat 4), only 120 odd Kg, about same as EJ series 4 cylinders.

only problem is these engines are not very well documented, few K to buy even 2nd hand, have some issues with cylinder warpage, but I believe there are fixes for that.

dont know what pitch, but it was the early alloytec with the two bike looking chains over the cams and the morse chain down the bottom.

its an interesting topic this one, because i had the alloytec 190 with the apparently dodgy chains on it and in 240,000kms i never had an issue, and my brother has purchased the car and he hasn't had an issue thus far 6 months down the track almost.... my mates mechanic workshop has done quite a few of these and all of them were alot less kms than mine and also very neglected inside, makes me wonder if all the stop start they get is just as much to blame, whereas my ute always did long trips so maybe that helped ? i definately think constantly cold starting wouldn't help them ?

[vlad01]

oil lubricates, sludge doesn't.

its like most V6 do the bottom end because of sludge.

[Jayme]

maybe it has a lot to do with service intervals? the holden interval is like 15000k, how often did you change your oil? perhaps the long service intervals wore out the chains? or maybe you were just lucky!.
my main chain was about 20mm longer than the new one that replaced it! but the main thing causing the rattle was a broken tensioner ratchet. instead of holding tension when the oil pressure dropped off, it went loose and during cold start rattled until oil filled the tensioner and took up the slack. if it wasnt for that, I might not have known to change it at all.

Your probably onto something there. I have seen pictures of alloytecs with serious sludge problems around the top of engine.

I believe the alloytecs have extended service intervals? Probably ok for your type of driving but a lot of stop start/short distance stuff just isn't good for oil.
