I bought ANOTHER 928 and took it to these guys. What's wrong this time? 

Thanks Neil. There's a heap of 928 (and 911) content on the channel already, including 17 episodes so far of my heretical 928 EV conversion which is progressing slower than I'd like. Cheers to you too. Don't worry, as I reach for my pullover down here it's getting warmer every day over there.

Indeed!

Por favor, podrías compartir algún especialista en 928 en España?? Saludos de un 86’ S2 desde Murcia

Porshcar en Sevilla, te anticipo que sera muy difícil que te lo coja.......Es una pena, pero es una realidad@@JuanDiegoNietoGonzalez

Glad you enjoyed it

Yeah it's not an ad, and we don't want to slag off at the new super synthetic oils because in the right car I'm sure they're great. For the record, Bruce for decades used to use Valvoline GP50 20W50, as per the owners manual, but no doubt there were other good mineral oils of the same grade. It was and remains important that the oil has a high ZDDP level, but this is hard to find as the Zinc has adverse affects on catalytic converters and emissions (cat.converters only came into mass usage in the mid 1980s). Hence the ZDDP was phased out or reduced in many oils. That particular formulation is no longer available I believe but BB is clearly happy with the Gulf one shown. And if he's happy that it performs well, then I'm happy. And it wasn't expensive. Also woth commenting that at times Porsche race cars have been sponsored by various oil companies proudly shown on the car's livery, but they were actually running a different brand in the engines.

Indeed. To be clear, and for peeps seeing this comment out of context, we were talking about wheel diameters.🤭🤏🚙

@@inCARnationAustralia LOL. Did you see my other comments regarding rennlist and LandSharksOz? For some reason they are not visible to me.

@@randyvfromtheperch I don't think I did Randy.

Yes evidently seats retrimmed with "leatherette" vinyl I think, and cloth of course. But dash original leather.

@@inCARnationAustralia Interesting, because I think pasha was paired up with vinyl more than it was leather. That's probably the original specification then.

@@chesswizard31 You're probably right, thanks.

Sorry 🥴

I can't speak for Bruce and I know he won't want to go to print making comparisons between brands. But Motul is a quality product. If it's a mineral 20W50 with ZDDP for sure it'll be a good product.

@@inCARnationAustralia great thank you for that information. I just heard that the ZDP eventually clogs up catalytic converters. Doesn’t the 928 have those ? Or maybe it’s just the American delivery ones that came with cats. Perhaps Australian ones didn’t back in 1984 or so.

@@jasonknight5863 I am definitely no authority on this but as I understand it 'clogs up' is probably overstating it. Yes manufacturers reduced it because of the detrimental affect Zinc has on cat converter. But it's not like they suddenly stop working or fail emissions. Yes as you say, early 928s like mine don't have cats but later ones did.

​@@jasonknight5863if your car isn't burning any oil then your cats will be fine, or so I'm told anyway. I've been using it for 13 years in my 85 928 and the cat is still good.

I wouldn't like to guess - I'm no expert. My first suspicion would be a burned or bent valve. But yes head removal is obviously much less work. 50 lbs is very low - I presume all the others are over 100. Can I suggest you get someone to do a leakdown test to determine whether it's more likely to be a valve seating problem than a rings problem. Also a camera scope to have a look at cylinder walls and valves. So most likely causes - either rings, valves or head gasket. How's the oil and coolant looking too? You really don't want to be doing a bottom end rebuild if you can help it.

@@inCARnationAustralia ok, I appreciate the reply. I haven't actually looked at the car just yet, I was just trying to gather any general opinions beforehand. Yes, I will certainly scope the cylinders and do a leak down test. I appreciate it.

Sensible suggestion thanks. But yes, cam belt timing and belt tension are both OK. Definitely not out by a tooth.

Hey Randy Not sure what's gone wrong. I sent a couple of replies, from separate email servers as it was clear you didn't get the first one. Maybe please check your spam. Thank you for the list of links, all great resources. Yes I was part of the landsharkoz group when Len Z started it. I appreciate your support and help, and let's try again.

Yes it's there on the channel details. But it's stuartgreaves928 at gmail dot com

@@inCARnationAustralia OK, will send.

@@inCARnationAustralia sent the email. Please respond to it confirming receipt and if you have any questions/comments. .

@@randyvfromtheperch Hi Randy, yes received email and responded this morning. Cheers!

Hey Randy. A couple of email replies sent. I hope you received them.
