| 532486 | 2007-03-13 02:26:00 | hey everyone - ive got a small question about my car - its a 1996 Toyota Trueno with the 4-AGE 1600 BlackTop 20 Valve engine in it. - i bought the car back in November and have changed the oil once in it (next oil change is due in 2-3 days :eek: ) but ever since i have bought it i have noticed it burns a bit of oil - not enough to see any blue smoke - and im 100% positive its not leaking any. i have talked to a automotive shop down the road from my work where they specialize in tuning and modifying Japanese cars - and they all said that this is normal for this particular engine (they also told me it has VVT-i) bonus! :p and that when they do burn oil its usually on a cold start where the rings haven't expanded yet and also when you are giving the car death (hi revs using VVT-i) - now is this true? can anyone here verify this? i find with my travelling (at least 500KM a week) im putting in a wee bit of oil into it every 2 weeks (after 1-2 weeks the oil can go down to 3 quarters full or less and i top it up to full again) should i be worried? i don't mind topping it up and keeping an eye on oil levels e.c.t as long as its the "normal" thing for this car\engine cheers for any help guys :thumbs: MAC_H8ER |

I know that for my Curren and my friend's old (1985) Corolla FX-GT, very little oil was used- barring oil changes, my car has used only a few litres in the four years I have had it . Having said that, there is an internet forum for Toyota owners, and they will be able to advise you on this . Go to www . toyspeed . org . nz, post your query there with the model/ engine details (found on a plate on your car's firewall) and the type of oil you used- in particular Mr Revhead should be able to assist (and tell you whether you have VVT-i or not) . As for whether the tuning firm is telling porkies, I doubt they have any reason to lie unless you purchased it off of them, and being a tuning firm they will have knowledge of any quirks with that engine- toyota 20-valvers are popular! :) 20 valves + High revving = more moving parts moving faster, so logically I suppose it would burn oil a bit quicker than most . . . did you get the car checked before you purchased it? What I do know is that you should be waiting for your engine to warm up properly before high-revving it . High-revving cold engines (modern or not) will damage them, and 20-valve engines are expensive to repair . The engine block is made of either aluminium or alloy- either way, once it's damaged, throw it away . Hope this helps! |

| 532488 | 2007-03-13 02:46:00 | Use you nose . . . . If the smell of the oil is sweet and thick . . . and not really sharp and nasty, then it's likely the rings, as that indicates it is burned during compression . If it's sharp and might make your eyes water and smell really nasty, then it's usually valve guides . . . in this case usually exhaust guides that are leaking down the stems and the oil getting really heated, but not burned in compression . . . kinda like burning oil in a pan with a lot of heat . If the smoke appears only after accelerating after a long deceleration, it probably is rings . . . . as guides or valve seals are not likely the culprit them . A stuck PCV can also be a problem here . . so check it out first! If the oil appears right at starting up from a long idle at a light or crosswalk, it probably is the valve guides or seals leaking . Oil smoke 1st thing in the cold morning is usually something else . . . does the "smoke" linger or dissipate rapidly? Coolant can look a lot like oil burning too . . and it shows up after a cold-soak and the night before the cooling system was pressurized . . . letting coolant into a combustion chamber . Does it use coolant? It's not supposed to! 20 valves? I don't know that engine . . is it 5 cylinders? (Gads, you retire for a couple of years and the engineers go nuts!) |

| 532489 | 2007-03-13 02:53:00 | yeah - you cant smell any burning oil - just after 2-3 weeks the oil level is down on the dipstick - i use Castrol Magnatec oil too 10W 40 i think it is?? and to surferjoe - its a 4-pot 1600cc engine - 5 valves per cylinder :eek: BTW i don't rev it when its cold - it just feels too cruel to do that to a car lol on a frosty morning it will rev at 2000rpm with no throttle whatsoever - on warmer mornings its 1500rpm for about 15 seconds then it sticks to 980-1000rpm and to sick puppy - thanks for that link to the forum ill give them a shot also to surferjoe again - me and my dad got this tested and there is no visible smoke at all - whether its idling or sudden revving - its just had a tune up too lol |

| 532490 | 2007-03-13 02:55:00 | As far as I know the 20v blacktop 4AGEs definitely have a form of VVT, but it's not the same "VVT-i" that's in other toyotas. My redtop 4AGE blew the rings and burned a huge amount of oil in the same way yours is (Being young and male I thrashed that engine every second it was alive, lesson learned), so I'd definitely get the compression checked for starters! |

| 532491 | 2007-03-13 03:19:00 | Do you need to keep the oil level that high? Usually it's ok if the level is between the upper and lower marks. Topping up to the upper mark was a service station thing to sell small amounts of oil at high prices. | PaulD (232) | ||
| 532492 | 2007-03-13 03:42:00 | yeah - but my dad reckons the amount its using is"F*ck all" and hes not worried about it all (he used to be a mechanic and my granddad was a full time mechanic and raced BMW's for a few years) and they both think its fine - my granddad gave it a full check over before i bought it and he said that i would be hard pressed to find a car like this in such good condition - so if they arent worried - and the tuning shop aren't worried ( i did int buy it from them) - should i? it runs really well - no rattles or ticking noises | MAC_H8ER (5897) | ||
| 532493 | 2007-03-13 04:04:00 | MAC_H8TR: ".....ever since i have bought it i have noticed it burns a bit of oil - not enough to see any blue smoke - and im 100% positive its not leaking any....." Hmmmm? I fall back upon my first impression that somehow you noticed something out of the ordinary with that statement...if it isn't leaking oil as you state, and it isn't smoking (as in burning it) then there isn't anything to NOTICE...right? Somehow, I feel like a trout. TY...:blush: |

| 532494 | 2007-03-13 05:08:00 | heh - well it isint leaking any - we put big sheets of cardboard under the car e.c.t - how else can it go down apart from the engine burning it? i do notice that when i open it up (e.g passing lots of cars) it uses more oil - but if i drive quietly it uses stuff all - but it still goes down so im stumped :blush: | MAC_H8ER (5897) | ||
| 532495 | 2007-03-13 05:40:00 | I have a Toyota with a 4A something 4 cylinder engine. Its done 290,000Km. It uses no oil at all. Its had 2 oil changes since I bought it and needs no top ups at all. On frosty mornings I get in and drive off normally. I don't rev the **** out of it, but neither do I mess about either. I just go. Last Toyota I had didn't use any oil either and that had done about 170,000Km. If it burns oil then the motor needs attention. Or you could just ignore it, its not a lot..............We had an Austin Cambridge that at the end of its second motor used to need 4 litres every week. It vomited enormous clouds of blue smoke. Thats when you need to start considering motor repairs or replacements............:thumbs: |
