D16 Injectors

Recommended Posts

In case anyone was wondering, a 6-pack of injectors for a D16 is $4600 from Volvo.

 

I dropped my 730 off at the dealership to diagnose my fuel pressure leak. It was isolated to being in the head. After pulling the injectors, one was bad. I opted to change out two more that were close to out of spec. The other three were good.

 

So, I got to work extra early today so I can pay for my repair bill. :angry:

Guys with the Volvo motors remember to ask the parts guys about the "new style" injectors.

It really only helps to go to the "new" style if you have to replace all 6.

According to info that is available these new injectors have a longer life span than the "older" style.

Just something to keep in mind when you are talking to the service manager about your injectors.

Start adding to your "piggy bank" cuz those other three injectors may not be far behind.

Did they happen to tell you how they determined a good injector from a bad one?

Do the injector "cups" get changed with new injectors?

You're right about the new injectors. However, if these last 600k miles like the originals, I'll be fine with them. :D

 

Apparently, there's some kind of test they put them through outside of the truck, which is why they had to pull them out. They actually hook them up individually to test, I believe. I didn't ask a lot of questions as I was trying to regain consciousness while getting up from the floor.

 

Yes, they change the cups with the injectors.

Britt, Bummer on the injectors but now you are good to go without that pesky fuel pressure leak. How have you decided to store your ramps ? Charlie

 

Charlie, I cut some new parts yesterday that solves the ramp storage problem. It also allows me to build some very high quality ramps (14" x 16') and store them "interlocking" in the ramp cavity. These ramps will use 2"x3" .25" wall aluminum tubing. They'll be great for loading the Smart or even significantly heavier vehicles if necessary, as I will probably rear-load some RZR XP4 1000 race cars at some point (for transport w/o 5er).

Was the $4,600 parts and labor? (hopefully).

bmzero - I have a D16 engine. What were the "faulty" injector symptoms? That is, what did the engine do or not do that was irregular?

I was losing fuel pressure. Driving, it wasn't noticeable. Idling, it would surge and was pretty obvious. I did not expect to need to replace 3, though.

How did you know you were losing fuel pressure? Is there something in the diagnostics center?

 

Idle surging! Oh krap. Smetimes mine surges at idle! I call it a loping idle.

At idle it wasn't a smooth sound. It would start with a little hick-up, and in 4-5 minutes it was sounding like a hit & miss engine with a miss.

Right, and if I idled the engine up, using the cruise control start/stop switch, it would run pretty badly.

 

I don't know if these conditions are necessarily tell-tale signs of bad injectors, though.
