Advice URGENT 3ZZ Engine !!!!

Postby Jon Gill » February 23rd, 2011, 7:06 am

A friend has a 03 NZE corolla. He has to top up oil every week. Its not smoking at start ups. No oil leakes any where, the oil filter is tight, no leakes by the drain plug, not even by the bell housing. No leakes by the valve cover either !!

I did a search & someone mentioned bout a stuck PCV valve. This was never changed as yet as I've asked already.

Mobil 10W 30 synthetic oil used & changed regularly.

Mileage approx 110K.

Can someone advise.

Much appreciated.

First step would be to replace the PCV valve.
A stuck open PCV will cause oil loss.
See link in my signature for more causes of oil loss.

When changing the oil again, dont use mobil 1. the formula has been changed and is not as good as it once was and because of that you tend to get a high burn off, i'm not saying that's your problem, but it could be.

i had the similar problem with mobil until i changed to amsoil with the same engine.
you can search for lab tests results online and see for yourself. Use amsoil.

when u say top up every week, does that mean that if he were to leave it for a month it would consume all the oil on the dipstick? I used to consume all the oil on my dipstick within 1 month and that was due to worn rings. Maybe let him try switching to a mineral oil like a castrol GTX for the time being until he can do a rebuild or buy a bamboo engine.

I would recommend replacement of the PCV valve every 40k km.
Never saw a recommendation for replacement of the thermostat, but now that you mention it, I would recommend a change every couple years on older vehicles. Replace coolant yearly.

Where can i locate the PCV in my 3zz. Not too sure, I am burning oil in a similar fashion and also realise that Mobil burns out very fast as of late. Switched to Castrol and it actually burns less but still burns none the less.

Please advise.

stay away from castrol... you know how some ppl say that toyota engines tend to build up sludge..well castrol does that very well....

you're better off using royal purple or amsoil..... 10w30...

Castrol shart up my engine. Sludge like that. Messed up some of the sensors and cant get replacements not even universal works. Guess i had to pay to learn for being cheap.

I changed the PCV last week. Got it from Gobins in St. Augustine & paid $75.00. The brand is Sankei & made in Japan. The engine has stopped burning oil now.

662-8781.

hey morning
I have his same engine and I plan on changing the pcv valve soon. The one you bought for it, was it the straight threaded one like this?
http://www.carid.com/images/wp/genuine/ ... 376oes.jpg

or the angled one like this
http://assets1.fcpstores.com/public/ass ... 1274388689

mine currently has the straight one and one place I went to buy only had the angled one without threading.. Not sure how this would work..

anyone else please free to comment/advise
