Re: **Loose intake butterfly screws**
well i had it in to nissan today, they stripped off the head, and found one screw missing from cylinder 1's butterfly plate , they did a compression test beforehand, and all was good, within specs.
there was no obvious damage to the cylinder or the bore, and the head seems fine, however they recommended i had the head sent off for checking, so thats being done next week.
if that passes ok, they will put it back together (with a new screw, and ive asked for all of them to be locktighted), and fingers crossed it will be ok, they seem optimistic, however it will still see me down approx $1700-1800, so for anyone else thinking about $300 being too much to check the screws, ask yourself, if you could find $1000's if it went wrong?

Re: **Loose intake butterfly screws**
Luckily it looks like it got sucked out of the exhaust before it caused too much damage.
Fingers crossed.

Did they give you a copy of the compression test results? If not, ask them for a copy and we can tell you if it's within specs or not.

That is a sensible thing to do as it is sometime almost impossible to detect a hairline crack in the cylinder unless tested further.

If it passes OK, my advice to you is to sell the car! None of the xtrails with missing screws recovered from this and the affect will materialise with time in a form of excessive oil usage and loss of power.

Re: **Loose intake butterfly screws**
Nope Paul, these screws are located in the lower intake of the engine block itself at the back of the engine head and there are 8 of them. Have a look at the photos in this thread for details.
