Took truck in for initial service. Have a question about something I overheard

did you ask if you can just go for the 35,000 and 45,000 mile service intervals due to how much cheaper they are?

 

Thank you

 

Haha yeah.
What shocks me a little is the price for the 30,000 mile service. I'm looking at what they do and the only thing I see additionally is change the engine air filter that isn't done at 10,000 or 20,000 but it's $100 more.

Also $109 for an oil change and tire rotation seems a lot.

I already have a spare air filter, cabin air filter, a few spare oil filters, set of wiper refills and 3 five quart jugs of oil on the shelf. So you know I already don't plan to buy their services.

 

Biggest dealer ripoff imo, is fuel injection/throttle body service. Just run top tier gas or E10 fuels. Sea foam works great for cleaning off carboned up valves, and piston tops.

 

Catch can....keep the carbon out of your intake

 

Interesting that that's a thing for gas engines. I had a pro-vent 200 on my Liberty CRD turbo diesel. What kits are there for the Tacoma?


Never mind $169. That buys a lot of seafoam

 

Its a thing ever sense the engineers starting venting the crankcase into the intake to conform to EPA laws. This caused problems with carbon build up in direct injection engines before dual port injection was added. Still not ideal to have hot dirty air exhausted into the intake

 

Catch can is another useless thing if they are so great why doesn’t it come as standard equipment?

 

I wonder how the genuises at the dealership diagnose this dire carbon build-up issue; especially when you are not being charged for the labor to determine that you have a problem.

 

It's a carbon build up, as others have said, on the recirculating system that basically pumps exhaust back into the engine. The so called EGR valve. Think it has to do with dealing with incomplete combustion. Technically, the valve that controls how much exhaust flows back in gets clogged to the point it stops working. The effect is a loss of some mpgs. I had a 350Z that would cake its EGR valves quickly. Usually cost me about 2 to 3 mpg when clogged. Took the engine about 2 hours of high speed driving to re-clog it. Wasn't worth the cost to clean it. Some here are talking about a related problem where the back of the intake valves (different set of valves) will gunk up. The catch can mod is suppose to deal with this. All recent engines suffer from it including the old EFI based engines. It wasn't so much a problem for them because fuel injection sprays the back of the valve with gasoline washing the valve (not the EGR valve). Direct injection does not do that. The injector is screwed into the cylinder itself so only air (and the crap in your crankcase (PVC) plus the recirculated crap from your exhaust (EGR)) passes by the valve. This causes a build up which is why most DI engines now use hybrid injection where it has both sets of injectors and will spray the back of the valves at some interval.

At least, that's my understanding of it. Best I can tell if you want to avoid all that go buy a 60s or earlier era vehicle.

 

Just in case anyone doesn't know this... it cannot prevent a mechanical over-rev with a manual transmission if you do a "money shift" -- like shifting out of 3rd gear at 75 MPH and accidentally grabbing 2nd instead of 4th. It's probably not as much of an issue in a long-throw truck transmission but was kind of a thing for awhile with cars like the Acura RSX-S that had short-throw shifters.

 

Probably due to the epa bs

 

Your doctor lubricates your shaft for $200?

 

Could be a throttle body?? Sometimes they get gunked up.
