Replying to: apptun (Apr 04, 2008 6:37 am) The only thing a cold intake will increase is the noise in your cab and the silicone in your oil. But hey all the truck owners who swear a marked increase in seat of the pants power with a catback and air intake can't all be wrong can they?   Toyota sells a supercharger. I'd have the dealer install that and be done with it. That way you'll have the fastest and quietest Tundra on the street.

Replying to: thomasdubya (Mar 27, 2008 7:00 am) If you look in your owner's manual, you'll see the interval is every 90,000 miles, so you are long overdue for this service. Also note that the 3.4 engine is an "interference" engine -- meaning if the timing belt breaks, you will have pistons hitting valves. If that happens, you'll be looking at either finding a junk yard replacement engine, or stepping up the the plate for thousands of dollars in engine repair.   Change the timing belt & water pump, or sell the truck! You could find an independent garage that would do the job cheaper, but I'd be very cautious there, especailly what brand of parts they install I've alway used genuine Toyota parts on maintenance of this nature. Good luck, Steve Replies to this message: thomasdubya (Apr 07, 2008 3:34 am)
#39 of 73 2008 Tundra Purchase by toddhm Apr 06, 2008 (8:12 pm)
Hello all, I am considering the purchase of a 2008 Tundra 5.7 that was manufactured in late 2007. Have the issues with the 5.7 (knock, etc.) been isolated to a certain period of production, and if so, after what month of production have the issues been addressed and corrected on the assembly line? Is there a way to check the VIN on the particular truck I am purchasing to ensure that it is unaffected? Please help.....

Replying to: market525 (Apr 06, 2008 6:44 am) I actually did some research on my own after posting the thread.What you said is correct.I contacted an independant garage to do the work and saved approx $300.00.All the garages that I contacted recommended the water pump replacement along with the timing belt replacement.the pump was genuine Toyota bur the belts were Gates.The water pump actually had a leak and was calcifying.The timing belt almost looked new and the 3 drive belts had little wear.Nor bad for 120.00 miles.will certainly repeat the procedure in another 100,000 miles

#42 of 73 07 Tundra Settling/Grinding noise in right front end. by rbudinich Apr 14, 2008 (5:56 pm)
My 07 Tundra makes a Grinding noise sometimes when I make a slow right turn. When I back out of my driveway and put it in drive it does it every time. It's definitely not coming from the engine. It sounds like its coming from around the right front tire. It never does it while driving on the highway. It seems to be noticeable at right turns most of the time. It's like a rough/settling/grinding sound. Any help would be appreciated.   Thanks, R Budinich

Replying to: jimmyg8 (Apr 14, 2008 3:37 pm) How was the diagnose made as piston slap? My dealer swears there is no problem!! They don't even hear the noise! I am currently trying different oils to see if it helps. I have 30,000 miles on my truck - the noise is not any better or any worse. I make sure anytime I have service done that the complaint is noted on each work order.

#45 of 73 oil pressure by kpg712 Jun 02, 2008 (5:20 am)
I just bought an '02 tundra with the 4.7 engine. My question regards oil pressure. I have noticed that when the truck is at idle in drive the oil pressure drops to the first hash mark on the gauge. When I accelerate from a stop the pressure increases to about midway on the gauge. Is this normal for the pressure to drop that far when at idle? The truck has 52,000 miles on it & is in great shape. I don't know what weight of oil is in the engine, but it looks clean so I'm assuming that it's was changed recently at the dealership. What oil do you guys run in your Tundras? Should I switch to synthetic? This is my 1st Toyota, I traded in a Dodge Dakota for it, so I don't know squat yet about the Tundra. Thanx for your help.

Replying to: csky (Mar 31, 2008 6:02 am) Don't know about the exhaust per se, but do like the tires I put on mine. They are the Bridgestone Dueler AT/Revo. Got them at Tire Rack on the internet for a lot less than the local dealers. And then had them installed at one of their recommeneded installers. They will even ship directly to the installer. And if you ever need winter tires the Bridgestone Blizzak are like driving with chains (not quite of course, but really make a big difference). But I change from season to season as the Blizzaks are a true snow tire and don't get the tread wear of a summer tire.
