Hey I've been having random starting issues and after it finally showed a diagnosis code I removed the cas - and I found the the exhaust cam bolts have rubbed against the cas! Am I missing a gasket or something to give it more room?

I would have hoped the mechanic would have noticed when they were adjusted!

Well when I got it back from the tuner it had new bolts on the cas - so I'm thinking they replaced the original and didn't put washers back on!

I think I will be having words with them....

Wow.

And looking at it it appears to be set to zero. Bit hard to see in the photo though.

I think it has a small adjustment.

I've put it all together and it still won't start - the injectors ticked when the cas was spun, and there's spark in the plugs - so fuel problem?? Or would the replacement cas put the timing too far out to start it????

Piggaz is on the money. No washers inside that rubber gasket causes the cas to get too close to the cam gear. It doesn't look like there is any of the washers inside that gasket in the pics.

R32-25t - I think that mark is where a washer used to be as the gasket is pretty hammered!

double check that the input shaft for the cas hasn't snapped off

Yeah the input shaft locator is broken off in the cas - so I'm trying to line up the new cas into the shaft, but it's bloody hard!

Ah I can see what you mean now I'm at the car - there is a small washer inbuilt into the gasket on the cam cover - if this is all that's needed I'm confused how the cas was touching the cam bolts....

can happen if the wrong washers are in there (not thick enough) but hard to say just from the pic. They look right, but you might be best off doing some measurements I think. Measure the thickness of the washers, etc. If you can source another CAS (cheap second hand one might be best) and put it in the car then turn it over by hand slowly and listen to see if it rubs it might tell you a bit more. I'd order a new seal and washers, not that expensive.Then see if it still hits

I've now replaced the cas - as it was scored on the inside.

I have got the car briefly running with it all together - and I think it is clearing fine as no marks are on the new cas so the gasket with washes included must be fine.

On reflection, ages ago I had the car running without the cam cover for a short drive, and didn't hear / see it rubbing, but I guess it must have been - a lot of damage with only 10mins of running!

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
