Is this normal oil consumption?

red2010z

I hear ya boss man. But I am the type of person to raise hell over something like this. I understand stuff happens. But back to back is uncalled for. In my profession mistakes can cost losing peoples life. So I guess I just take major mistakes like this to heart.

Best of luck and hopefully they cover the bill.

I just got the car back and all seems well again. I decided to contact the mechanic directly instead of dealing with the service adviser because I had left the car at the dealership on the evening of May 2, 2013 and still wasn't really hearing anything about it's status. When I called the tech, he said that he had driven it a bunch of times and that he couldn't duplicate the issue. He was keeping it there longer to observe it but that he didn't want to hold me up. So then I explained to him what I was experiencing with the clutch pedal becoming sticky and not returning to the "rest" position. He said that the service adviser had not explained the problem to him like that. Furthermore, he immediately quoted the technical bulletin which says to bleed and replace the system with GTR fluid. I ended up just paying for the fluid but he wouldn't charge me for the labor. I hope this is the end for now...

Good luck. When I flushed my clutch fluid and replaced it with Ate Blue, the pedal feel greatly improved.

Quite the saga.

When they pulled the engine who knows what they disconnected. They may have disconnected the clutch line to get it out of the way. If you let it go dry it can be a bitch to bleed thanks to the hydraulic slave trapping air.

Anytime the clutch disc is pulled Nissan recommends replacing the slave since it is sensitive to contamination. Since they had to pull the clutch off the old engine in theory they should also replace the CSC (which is mounted to the transmission). This rarely happens though.

During the first 1.2k of mileage on the new shortblock, the motor didn't eat any oil probably because I kept the revs under 4K (following break-in procedures). After 1.2K, I had the oil changed and for the last 950 miles, I've been driving the car normally as I would with no reservations. Unfortunately, I am noticing oil consumption again. I told the tech about this and he added a BG additive.

Hopefully, the oil consumption will decrease and then stablize between the next few oil changes.

1) If you need an additive, something is wrong and needs to be fixed. Additives are only a temporary "fix."
2) 99% of additives are snake oil and either do no good or make things worse.

If this were an old engine that was on it's last leg, some type of additive might be beneficial and possibly get you a few more miles out of the engine. For a new engine, additives shouldn't be needed. The additive will only mask the problem (if it does anything at all).

My replacement engines consumed oil until around 5-6k. Give it a little more time and keep an eye on the consumption. You should notice it get smaller and smaller with regular driving.

OP, you need a crate motor...

I was unaware that when I bough my z used with 10k on it the motor was replaced less than 500 miles before I bought it, I learned this when I took it in for a OC complaint. Keep in mind I am a service advisor for Honda, so I know the guys there and most of the techs personally, one of their tech worked for us a one time, and is an old guy and knows his s*$t. He told me these VQs do not break in well on the the crap Ester oil or synthetics, he had me use regular dino oil for 2 oil changes, it drank 3 qts of Mobil 1 in 1800 miles, thus why I took it in. Now it may have used .5 qts in the last 3000k on Valvoline synthetic.

Dropped her off at the dealership last night. Tech said this morning through some investigation that oil was seeping past a bolt for the VVEL right cover. He tightened it down and put liquid gasket around it.

Let's see if this fixed it.

Man, after all the problems I am reading about, Oil consumption at 32k, clutches with the life span of a butterfly etc. I am wondering if I made a mistake buying this. (2013 6mt+spt) I love the car but after reading all the stuff on this forum it seems like a time bomb.

I guess the question is how much of this perception is based in reality vs the total number of cars out there and who posts about issues? Are we talking 50%? 2%? 100% on the clutch issue sooner or later or what?

I would like to have rock solid confidence every time I am pulling my Z out
but not inspired by what I read. My gut feeling is this is just perception because you read about specific events and the majority have no issues.
I hope at least.

You're talking about a small percentage of people on an enthusiast site. However, that's also not counting the non-enthusiasts who have had problems.

The oil consumption issues are very rare. The clutch hydraulic problems are common.

All in all, it's not an unreliable vehicle. It does have its quirks, however. Just drive and enjoy it and don't worry about problems until they happen.

Mine is at the Dealer getting replaced right now. Same deal, was supposed to take 2 days.. "problems with the Timing" ..then a wire related to the Timing was broken during install. been a week. supposed to be done tomorrow.
I have never tracked it or even ridden it hard. Every 1k miles the oil is COMPLETELY dry.. yes Oil does not even register. sad story...

avantgti7

I'm sorry to hear that bro. Keep an eye on them and try to establish a relationship with the tech.

You want oil consumption... My fellow service advisor had a vette that ate 2 QTS of oil every 1k miles... Gm told him to pound salt. Traded it on a Z. I've said it before I am in the service business I can list problems for every Honda in existence... All cars that are mass produced will have issues... Im on my second trans and the way it's going there will be a third... second gear sync will not line up at redline.... just grinds away. Agreed drive the car and enjoy it.
