intake manifold service

What about your muffler bearings?

If they mean a throttle intake cleaning due to gunk buildup from dirt and gasoline byproducts, then that's an actual service item and with over 100k it's time.

 

They are trying to scam you. Unless you feel there's performance issues, I wouldn't worry about it

 

If they are talking about the throttle body, you can do this yourself. A rag and carb cleaner wipe down the throttle plate and throat.

 

Did one yesterday. 10mm socket and a $20 can of Liqui-Moly intake cleaner. Does make a difference on our cars with high KM's but it's one of those things that has become popular lately....

 

Completed a vehicle intake manifold service. You need to do both for the best results.

The last time a sat in a customer service waiting area at one of my local dealerships, I thought to myself "how do these robbers without guns sleep at night will and the made up ramblings they throw at unknowing customers." The worst conversation I overheard was some service writer playing on the alleged or perceived unsafe condition of a elderly person's vehicle to them. It was nearly criminal.

Remember folks you can always defer or decline any service recommended. Jake, good job for pumping the brakes on this one. I believe the valve lash in these Atkins style motors are prone to leaving an oil deposit in the bottom of the intake manifold. It has been discussed on here several times over the years. Its not detramental to the health of the engine. Should your throttle plate become gummie, sticky or you experience driveablility issue it is a simple $10 DIY fix.

 

Don't know, most would just say "throttle body cleaning service" or similar.

 

RUN!!!!!! They are TOTAL SCAMMERS.

Ask them to show you, in the TOYOTA PRIUS MANUAL, where this service is recommended, needed, or suggested.

The answer is that, it is not.

 

Why not? It is hardly an undertaking. You just have to remove the air filter box lid and then the air filter. You can then look straight down the throttle body throat to see what the floor of the manifold looks like. They would have removed the air filter for a basic inspection to check the condition of it, anyway.

 

Intake manifold cleaning is maybe more warranted with third gen, due to both EGR and PCV dumping into it?

 

Total hogwash, an unabashed and shameless money grab attempt.

 

TB cleaning is also HOGWASH, unless the buildup is soooo very bad that the throttle plate is actually sticking/binding, which is a very rare condition unless the stop screw has been tampered with.

In point of fact, MANY TB assemblies have an "anti-fouling" coating that actually PREVENTS build-up of crud. These coatings can be and most often are, destroyed by commercial carb and TB cleaning solvents.

 

I've cleaned mine pull off the throttle body there two cooling hoses to clamp or and one air like normally if there trap in there the PVC valve is
stuck open
