Oil in throttle body

Not normal by any means, mine is always dry as a bone and clean, please don’t put out misinformation, he has an issue w/pcv valve or blow by. I build race and normal engines and can tell you, if you think that’s normal keep running your own truck like that, and let me know how fast your heads get gunked up and cause some catastrophic damage. I’ll watch for your post when you’re engine goes out trust me. I’ll be there to say I told you so!

 

Hard to tell if it’s headgasket from the looks, a compression check won’t help, if I were you I’d get the heads off and turn the engine by hand looking for scored cylinders if that’s not your case you may have a cracked head between a valve seat (common on overheated engines) so the heads would need a good pressure test. Head gaskets aren’t a common issue but possible. If you need a short or long block LC engineering has you covered they carry ATK engines they are trustworthy and have a pretty good warranty. Good luck! Looks like you caught it early enough to save it.

 

I stand by my statement. I would love to see your throttle body to back up your statement(without you cleaning it).

Had this truck since I drove it off the lot in '98. PVC valve is fine. It is an oil mist that will condense and coat the throttle body. The pic shows my cheap catch can (air water separator) that clearly has oil in it.

For you all who believe this guy, google "dirty throttle body" and look at the images, throttle body fouling is due to the oil mist, not the air filter. It's a closed loop system that is designed
to burn the oil in combustion process instead of venting to the atmosphere. EPA mandated.

As for me personally, my heads will not be 'gunked up' and have 'catastrophic damage' due to I run water meth injection just after the TB and all that gets cleaned.

I will be waiting for the "I told you so!" moment that you so confidently state that awaits me.

 

Elnip isn't wrong. The pcv valve definitely puts out an oil mist. A catch can works to keep it out of the TB but it isn't really needed. Catch can or not you should be fine. Heck mine vent to atmosphere (for now)

 

Yea..Oil in the cylinders doesn't necessarily mean head gasket..

Considering the amount of oil in the throttle body, that tells me the oil you see on the plugs has to be coming from the intake. There is no way that oil would go backwards from the intake in to the throttle body since the engine is sucking air and not blowing it out. PCV valve is the only way I can see oil go in to the throttle body.

 

Oil blows out unless it’s closed deck. I do more service than most would ever consider normal, and for good reason, I worked w/KTM race team. On the side hustles I would make money from people that don’t consider maintenance as a top priority. That said even Mobil1 5-30 only gets only 1k in my engine, my neighbors beg for my used oil! I can absolutely attest, I don’t have a dirty tb, “as stated”, and will gladly show my tb. My engine doesn’t have enough blow by to look like that as “normal” ever, and I do mean, damned ever! I’m doing valve cover gaskets and cam reseal soon, I’ll pm you, “friendo”, to show my spotless engine in and out w/o the cheese, I’m not hiding here. That’s not a normal tb if the engine is healthy. Op shouldn’t listen to you, I build engines stock and very upgraded, I am very lucky to do so as it is my passion and income.

 

Just a quick clarification. You change your oil every 1k?

 

Yessir!

 

Also I run Motorex during summer for 3k at 15+ a qt. I am a 1%er! I don’t give a ***£ bout money I don’t break down!, I help people more than AAA. I could have purchased a third gen and tricked it out, I could have a supercharged vette! I chose a first gen Taco because its a great vehicle and deserves the best imo, I am just a fan of them period, never been let down by an old Toyota.

 

OK "friendo", post it don't PM me.

 

... Changing oil every 1k miles is nothing more than a total waste of time and money. It's not a KTM that only holds one quart and needs frequent oil changes.

I agree with you that 1G tacomas are sweet... but not sure how the rest of the post is relevant. Also I will happily take your used oil

 

Lol, just because people can’t afford it, I’m being wasteful?, thats just a matter of opinion, Yeah I’ll spend 70-80 bucks to change into motorex and its not Just used in KTM bikes, Team Porsche uses this oil and no I don’t really care if people call it a waste. My buddy stupidly pays jiffyjob to put the terribble pennsoil in his big block SS Camaro and blows 140 bucks on absolutely shite! So who’s being wasteful me or the guy ruining his motor and pushing oil changes to the last mile or past. There’s an old saying ‘an ounce of prevention is worth a pound of cure’. Even Rich Casselli, Kurts pop had been turned back to Motorex by me, they would get Motorex free but would use crap rottella, once they were rocking Motorex they always made it to the finish line and the bike was still purring instead of a quick change on a six days event when they had been using rottella. Shit my Subaru only see’s Motul recommended by Subaru teams ever, and at 2k & 3k it comes out looking like crude oil, and that stuff is close to Motorex prices too. Top fuel engines get one pass on very expensive oil and it’s not recommended to even reuse that, so its a moot point if you don’t agree, just know if I see you broken on the side of the fwy w/a taco mine is there to help ya!

 

I don’t believe it would be polite to call you out publicly if you have engine problems, I would pm you and offer a helping hand and understanding. I’m here to help not make you feel bad. I’m a tough hardheaded oldie and unless we are all geniuses we can all learn from others experiences. Especially us old timers that know tricks.

 

Just out of curiosity, have you had oil tested before?

 

Yepsoy, w/ blackstone mobile 1 can last me 5k w/my drive style but I trash it due to suspended metals. Motorex tested at 5k & was told I could go to 12k but I don’t. Like said I worked diagnostics and have lots of certs and R&D under my belt and I preach prevention. Saves money not having lazy ass AAA to pick me up. Redline, Royal, Amsoil and Mobile dont hold a candle to Motorex or Motul. I budget for this l, others smoke a carton of cigs @50+ a week so.. Some drink a twelve pack a day, lol.

 

I agree that prevention is key, but you need to draw a line at some point. Hell, why not do an oil change every 100 miles? Guaranteed you won't find me broken down because of maintenance issues, and I don't know of anybody who's broken down because of an extended oil service interval.

I have plenty of experience working on high end vehicles. Previously I was an engineer at Singer Vehicle Design building $500K + dollar carbon shell 964's. I can assure you those owners have more money than most of us could ever imagine, and we still elected to change oil every 3K or before and after a track event. With normal driving oil simply doesn't break down that quickly.

It's your money, your vehicle, your time. Do what works best for you.

 

I guess comprehension isn't one of your strong attributes.

 

Let's all be civil. This thread is about the OP having a problem with oil in the throttle body and not a who's engine is cleaner and oil frequency change debate.

Let's be kind to each other here and not thread jack. We are here to help the OP not argue.

 

Update: Did a compression test after warm up and all were about 150, which I know is low. But also I did see steam coming out of #3. Thoughts?

 

Well said good Sir!
