Re:


Hi Samuel,

The DIY preventative measure is here in this thread and this only applies to the T30 models. The T31 lower intake manifold is completely different and doesn't have this issue. Yes, this is something that can be done as a DIY although not everyone can reach the area in question and the risk involved in dropping one of these damn screws into the engine block are far too great and if this happens, the entire engine block would have to come-out and stripped open.

I said 5 years because I didn't have any issue or any noises for the duration of when these butterfly screws were last checked by Nissan, but due to the heat in that area, the loctite may get affected much sooner, but 2 years is a bit too soon.

I'd give it one more year Julie, 38K is not that much, I have done about 60K since they were done.

Re:


If a screw does drop into the cylinder block, you can always use a flexi magnet with a long handle to get it it out.

Yeah, you can only hope it'll be reachable enough for the magnet to catch it.

Re: **Loose intake butterfly screws**


I did mine last night - 151K on the clock, 02 model. Turns out, the loctite fix had been done (bought second hand with 58K on the clock and I have always been putting off checking). Just over half the screws were turnable with a bit of effort, 3 of them still stuck in quite well. Red loctited the ones that could move. I guess that's why I haven't had issues with it, as it's done.

Did it in place with a strong magnet on the screwdriver which worked just fine, I wouldn't do it without a magnet on the screwdriver though. Only dropped one nut which holds the loom bracket on the back of the upper manifold, found it and screwed it back on. About 2 hours all up in place.

Next up over the next couple of months I will do the cam/crank sensor and possibly look at the chain tensioner, but touch wood things will be OK. Have had to do a new radiator at 150K (looked like o-ring between plastic bottom tank and core), all 4 wheel bearings between 110-120K but nothing else really "big" in the time we've owned it and just want to do what we think is a good idea to help it reach 250K+ kms

Re: **Loose intake butterfly screws**


Hi Daniel,

What symptoms are you noticing? Loss of power? oil on the spark plugs? bent spark plugs?

posticon Re: **Loose intake butterfly screws**


Loss of power, missing when idling (popping sound from exhaust) and also excessive fuel consumption. It has low compression on cyclinders 1 and 4. Nissan have suggested further investigation work would be required to obtain a better diagnosis of the fault however it may not be confirmed without the removal of the cyclinder head for inspection by a head specialist. Could it possibly be the butterfly screws problem as mentioned on the forum and has there been any upgrade on this problem?

Re:


They can use a camera to inspect damage if any, but you can also remove the spark plugs to see if any of them has a closed gap, which are signs of something inside the cylinders.

There has been no formal Nissan acknowledgement of this problem and they treat each case differently.
