Why did my Lexus ES 350 suddenly dump oil (VVT-i oil line)?

Short answer: On 2007–2008 ES 350s with the 3.5L V6, a sudden big oil leak with a low oil pressure light is often the VVT-i oil line bursting. VVT-i is Toyota's variable valve timing, and this line feeds oil to it. Early cars used a line with a rubber section that can crack and spray oil fast. Lexus ran a campaign (9LH) to replace it, but the extended coverage ended on December 31, 2021. Owners now install the all-metal line, which is a cheap part and about an hour of labor.

Symptom: A big oil puddle or oil sprayed under the car, a low oil pressure light while driving, or oil dripping from the passenger side front of the engine.

What to check first

1. If the oil light comes on while driving, pull over and shut the engine off right away. Don't restart it until you know there's oil in it.
2. Look at the front of the engine on the passenger side for oil sprayed around a small line that runs along the engine.
3. Ask a shop or dealer whether your car has the all-metal line. A line with a rubber hose section is the old design.
4. Run your VIN at lexus.com/recall to see whether campaign 9LH was done. Even if it was, some cars got an updated rubber hose, not the all-metal line.

Likely causes

1. Burst rubber section of the VVT-i oil line. On Lexus Owners Club, owners said the rubber part of the original line ruptures, and Toyota changed to an all-metal line in 2009 production.
2. Leaking line gaskets. The line uses small gaskets at each end that can weep, so they get replaced with the line.

What it usually costs

On Lexus Owners Club, an owner listed the all-metal line (part 15772-31030) and gaskets at about $31 and a dealer charging about $109 for an hour of labor. On Club Lexus, owners also put the metal line at about $35 plus about an hour of labor.

Is it safe to keep driving?

No. If the line bursts, the engine can lose all its oil in a minute or two, and running without oil destroys it. If you know you still have the old line, replace it soon. Verify with a mechanic.

DIY or shop?

Skilled DIY or shop. The parts are cheap and it's about an hour of work. Owners say the metal line fits all 3.5L engines of this family.

Recalls, bulletins and complaints in plain words

• Lexus campaign 9LH (limited service campaign, now ended): Lexus replaced the VVT-i oil hose on certain cars. The extended coverage document says it ended on December 31, 2021, so the repair is no longer free.
• Passenger airbag recalls 16V340, 17V006 and 19V741 (separate issue): certain ES 350s are part of these airbag inflator recalls. If your car is part of a recall, the dealer fixes it for free.

What owners report

• In Lexus ES 350 VVT-i oil line failures on Lexus Owners Club, owners said the rubber section of the 2007–2008 line ruptures. The campaign gave a thicker rubber hose, one dealer installed the all-metal line for free, and the metal line plus gaskets cost about $31 with about $109 for an hour of dealer labor. Toyota changed to all-metal lines in mid-2009.
• In VVT-i oil line burst on my car on Club Lexus, a 2007 ES 350 owner at about 113,000 miles got a low oil light at 45 mph, shut the engine off within about 10 seconds, and had it towed. The campaign had been done in 2010 with a rubber hose, which then burst. Replies said to buy the all-metal line, about $35 plus about an hour of labor.

My take

My advice as a former lube tech: on every 2GR-engine Toyota or Lexus that came in for an oil change, I'd look at that oil line. If it still had the rubber section, I told the customer to replace it. It's a $30 part that saves an engine.

Vehicle focus: 2007–2008 Lexus ES 350 with the 3.5L V6 (2GR-FE). The same line was used on other Toyota and Lexus models with this engine.

Safety / mechanic note

Losing oil pressure can ruin the engine within seconds. Pull over and shut it off. Verify with a mechanic.
