So I purchased my car a while ago and was told it had a rebuild But now I'm curious.. I asked the workshop that did the work/invoice and they said no idea or its fake Yet it's dated from 2003 so it was a while ago Someone told me to check compression and cold plugs Compression will just tell me the health?? Which I know is good made 218rwkw on 15psi standard highflowed turbo. The cluster reads 126000ks with a body/interior to match the only thing that makes me think it has had a rebuild is the sump has been removed (see pics) What else should I look for without taking the head off.

Curiosity killed the cat.

Are you saying that you have an invoice for the rebuild? Does it specify what work was done? And are you saying that the shop whose name is on the invoice say its a fake?

Your car is still going well 12 years later. Do a compression test and if all good find something else to worry about!

12 Years ago wouldn't matter much now as you don't know how its been treated since then.

Having the sump off could just be a bodgy fix it job

You could shove a camera down a spark plug hole but may not see what your looking for if oem pistons used.

Only thing you have seems like an old invoice the shop doesn't have any idea about.

Simply compression and leakdown test it, should give you the cylinder and valve seal condition of it.

Also note the cold and hot oil pressure for oil pump and bearing wear.

Other than that 2003 was a very long time ago.

It could have been the worlds best rebuild or even a brand new engine used but if the previous owner thrashed it, had a bad tune, ran cheap oil, didn't service it, leaned into it cold or drove it while it overheated, nothing but a rebuild will save it if it shows signs of wear.

Speaking of which i looked into a Toyota engines oil filler hole today with only 80,000Km on the clock and the whole inner surface was covered in crud from running it on cheap oil, service book was all stamped on time by a Toyota dealership too.

    • The old manifold was quite under the GTR strut brace.  The new manifold is quite [unknown] the GTR strut brace. The GTR strut brace was needed to clear the bonnet vents. The Old strut brace will almost certainly clear the new manifold, but not the bonnet vents. The old strut brace will almost certainly clear the new manifold, and the new bonnet without vents. But I am hoping the GTR strut brace clears the new manifold :p
    • On the bright side, at least you knew that it happened and remedied before anything happened. A friend of mine just took his Fiat 124 to a shop for an oil change and they didn't tighten the oil filter housing properly. 4.5 quarts spewed out and even after refilling + tightening the cap the engine has a tick now.
    • So, more pain. The FAST manifold is a little larger than the stocker. This is problematic because there really wasn't much clearance to begin with, so going from 'barely enough' well into 'no' is sad based on the external dimensions of the thing, even though where it bolts to the head is the same. Result is the fuel rails sit a good 25mm higher, and this is a bit of an issue with the wiring that runs behind the motor, and the fuel lines, and everything else. When pushing the manifold on, it required a huge amount of force to crush wiring looms to fit it, sensors like the MAP sensor are about 1mm from the firewall, and the FPR just has to bend ABS lines to be forced into place. After some brainstorming and some sad drinking, the loom for some reason ran from the grommet behind the ABS sensor, then to the driver side head, then back to the passenger side head. So all of this was pulled back and stripped, a few wires cut and rejoined, so that the 'branch' was now on the passenger side's head as below: Before you basically couldn't see anything behind the driver head. This is much improved! The MAP sensor is now pointing up (instead of at the firewall) Brackets have been made up for the rail. The rails are for a LS1, the manifold is designed around a LS2 as it's base. Which of course has slightly different bracketry and water pump clearance, hence the mods people need to do. Should be hopefully mounted tonight. I spent money on a new FPR that is slightly more compact than my Turbosmart FPR1200. The gauge has also been moved to the rail. There's also apparently an ORB to AN Union instead of the adapter, because the ~25mm of the current adapter is going to make the difference. Provided this all goes together and arrives today, it'll be the totally not stressful attempt to start it.
    • This seems like a pointless exercise. There is no E30 availability. Ongoing availability of E85 should not be assumed. Flex-fuel is the only sensible approach, so you can use E85 when and where you can get it, 98 when that's al you can get, and anything in between as you fill it up and drain it down. And if that means replacing the pumps, fitting a flex capable sensor/ECU/whatever has to be done to these Renault shitboxen, then.....so be it?
