working on my friends father's car. Asked me to find out why his oil light was coming on, oil was topped off and after driving for 10 mins, it comes on.

removed valve cover and found out why, went ahead and pulled the motor and will be breaking this bad boy down and doing a good cleaning on it.

Mileage? Oil type used?

ilikerice · 12-17-2011, 03:38 PM

has 107,000 miles, he did the normal 5k mileage services but went to quick lubes and used conventional oils.

silver_echo · 12-17-2011, 05:24 PM

The gel like that comes when you miss the 5k spec by a lot. With conventional oils, 3k is cheap insurance against this.

ilikerice · 12-18-2011, 05:07 PM

yes, but its funny how Toyota maint. intervals for Oil changes is 5k, and doesnt specify to use synthetic. So any "Joe" will use the cheapest oil on the shelf and change it every 5k.. even if you take it to the quick lubes, they still use the cheapest on the shelf also so they can compete with other shops at $29.99 for a quick lube. He bought it new. Says he did all the required maint. on it since he bought it. He has no reason to lie about it. It was his first "new" car he ever bought. Not like he is trying to convince me under warranty or anything.

Talked to some toyota guys and they said the 2az had alot of sludge problems also. I worked at lexus, so I saw a lot of v6 3.0 with sludge issues. and this doesnt look any different then what i have seen.

I don't feel so bad about spending $10/quart for synthetic if it prevents this. Though I do have a 92 Miata that ran conventional Valvoline 10w-30 for 150K and it's as clean as new under the valve cover-but it did get the 3K mile oil changes done by me. Great Photos of this situation.

My wife's Sienna (1MZ) has a similar appearance under the oil cap. We bought it used, but I know for sure that she has missed most of the oil change intervals. I'm sure it could use an overhaul, but I lack the skills/tools to do it myself.

Oil way past its service interval right there.

Doubt even "synthetic" severly hydrocracked base petro oil would have prevented that.

Service intervals are there for a reason.

Odds are if he is doing a full overhaul, he is getting all the internal seals and getting what can be cleaned steamwashed, and blasting/degreasing the rest.....

Yes and no. I am replacing all seals, i will be using brushes and a parts cleaner bath (not steam washed or blasting which would be a much better clean). Using pipe brushes to get the oil flow back to certain areas. I have not pulled the rod and cam caps yet. Will be replacing oil sump and pump as long as water pump while im down there.

again, I have done this many times before on V6 3.0 RX300 and ES300. Toyota states that when they disigned these engines they tried to save weight by making the oil passages smaller to make a smaller motor to save weight. Unfortunately even if you do change you oil every 5k with conventional oil, you run the risk of this happening. Not saying every 2az is going to do it. but the risk is higher.

I will take pics as I go because I am also sending them to the owner so he is also gets updates on my progress and understands whats all being done. Also he gets some cool before and after pictures. I am practicly doing this for free. All I ask if he pays for the parts. As long as I am not on a time restraint, I dont mind doing this stuff. Its fun to me.
