Hello,

I've been noticing this for couple weeks now. The engine has been burning oil due to worn compression rings and also causing blow by (oil going thru intake tube). Valve stem seals is bad too because when I take off after being at idle on a stop light for example, bluish smoke is present. I've diagnosed these issues so no need to go any further.

Any temporary solutions to remedy these issues? Any suggestions would be appreciated while I gather all parts for my rebuild in about a few months or so. Kinda odd I would deal with this than blowing a pair of headgaskets as it is common on these engines.

 

hg are not more common than oil problem. your engine is old and tired, you expect miracles?

best thing would be to change the engine to a low mile jdm , and then optionally on spare time rebuild your 3vz-fe and keep as spare. there are no, NO, other solutions that will work. repair or replace. and soon because you are polluting the air others breath

jdm engine usually are 30K miles and are around 800 bucks .not particularly hard to swap these engines. gives you a chance to replace clutch too

 

Thats true, Gonna search for a low mileage engine locally 1st before getting a JDM engine. That sucks that theres is no temporary solution at this point cause it'll take me awhile to rebuild the engine and money is a lil' tight too (raising money to purchase a home is the reason).

 

You are not mentioning the weight of the oil that you are using, nor how much oil you are burning. These are two important factors, but before going to the extreme of changing your engine, and assuming your diagnostic is correct, than first try changing to a heavier weight oil, such as 10W40, or maybe even a bit higher.

If you are lucky, it may mitigate your oil consumption. If however as I understand it, you also have blown Head Gaskets, than that's pretty much the end of the road for this engine.

PS: Check your PCV valve to make sure that its not blocked.

 

If you want additives, then two I've used.

Restore (just about any auto parts place)
Lubro Moly Motor Oil Saver (Napa)

 

Really?!? I had no idea a 30K mile engine is just $800. Were can we get one? We don't really need it, but for that price, I would love to have a spare.

 

lexmex, evidence?

pfb, hahaha you dont have any evidence tha will work

the truth is you have to fix it or replace it. there is no magic pill. sorry that all im giving you is the red pill, the truth one, that's how i live my life

limen, contact your nearest JDM importer, or one of choice. also scan ebay... in the mean time, if you want immediate gratification that I am not making up the price, here's just one example:

PFB: Headgaskets are fine, no internal o external coolant loss is present at this time. 10w30 is the oil I used from Toyota and recommended for this engine since I bought it back in March 2009. I also change the PCV valve when I purchased the car. May have to look at it again. I'm getting prices from my job to order necessary parts for the rebuild (OEM Toyota/Lexus parts).

 

that's a lllllllllllllot of work, and you might as well do a whole bunc hof stuff besides the rings and valve bushings....... my god man. wouldn't it be WAY EASIER to replace the engine altogether?

timing belt
valve adj
valve cleaning/replacing/grinding
rings
possible other engine work
valve guide bushings
oil change
coolant change
all new gaskets
exhaust gaskets
clutch[either way]
flywheel resurfacing/replacement [either wayhead]
head gasket and head bolts
hoses
water pump

im losing track. anyway, costs for costs its better to get an engine, factor in work too, and plus you end up lower mileage engine [which has many benefits including but limited to increase car value, works already while the other choice is that you can make mistakes doing all that work you're doing to fix your worn engine] ......... plus you get a new engine, you will start treating really nice and it will last a long time compared to the current engine you had no control over during its lifetime.

 

Oh no, I believe you. I didn't mean to make it sound like I thought you were fibin' to me. Thanks for the link, I'll keep my eyes open...

 

LL: most of the work will be performed by me using my discounts thru Toyota and machine shop if required.

 

What's your point? Does it cost less? Does it have the same risk? Which takes less time and how much time can you afford? I think that both the cost and the risk will be less with a JDM engine. Or, you might try putting in one of the newer bigger engines that toyota makes that will fit on that transaxle. That might actually be something risky, if you like risk, but may pay off in the end as far as wacky and fun. Isn't there a 3.3L? All you would need is a harness and a computer, possibly a couple motor mounts [if the engine doesn't come w/ them]. This is also a time you could turbo or belt driven supercharger your machine. I think I saw a jdm for 500. so, look around for 3vz-fe engine from japan, they are low mileage, typically.

 

U know, I once thought of ditching the 3VZ and do the conversion, 3MZ-FE 3.3L block with 1MZ-FE heads, harness, computer and E153 tranny from the Solara or Camry V6. Or boost? the 3VZ would handle boost better than the 1MZ engine.

 

our tranny already works with the 3.3 ..... and is geared better ....

and as far as boost goes, yeah, the 3vz-fe is beyond adequate, as long as you dont go crazy -- if you go crazy on boost, then you gotta swap the pistons and connecting rods, and head gaskets [and you might sw to head studs at this time].

its onlya matter of time. will it be you, or me, that does it to a lexus es 300.

[i say 3.3 because I do not want to make a mistake, nor confuse people, saying 3mz-fe. 3vz-fe and 3.3 are what i use instead of 3vz-fe and 3mz-fe. sorry if this annoys anyone]

 

I understand u well, u dont confuse me . Like u said it'll only be a matter of time to make our ES' very cool. Maybe on the cover of Modified or Super Street would do (daydreaming).
