I believe it would have been checked for straightness. Through the use of oil pressure and spring force, the lash adjuster maintained a constant zero valve clearance. I sent the crank into the engineering firm for checking and polishing. The dual fan spray pattern of the direct injectors is perpendicular to the piston travel with wide dispersion in the cylinder, which aids air and fuel mixture and therefore increases power and efficiency. And here I'm reading this thread and seeing people who didn't replace the timing chain until over 200K miles.
From what I can see, it seems as if this motor has run hot a few times, but got shut off in time before causing damage. If your truck is running like it always has for the last 112K miles, and isn't making any new strange noises, they're probably trying to take advantage of you. Oil-cooling jets under the pistons acted to reduce piston temperatures. Direct injection lowers the tendency to knock detonation and increases performance by reducing the charge intake temperature. I hate shops like that.
When in doubt, ask TacomaWorld first! It was this last, long trip that he was on, hat finally sealed it's fate. The connecting rods and caps were made of high-strength steel and nutless-type plastic region tightening bolts were used to reduce mass. To increase the sealing surface for better durability, a shim was added around the cylinder bore. The engineering firm I use are quite thorough. The engine's service weight is 174 kg 384 lb. Furthermore, the timing chains were lubricated by oil jets. This engine has special cast-iron cylinder liners cast into the block, which are a spiny type to improve adhesion between the liner and cylinder block.
I will try to get some better shots next time I get a hold of a 1gr job. Sir: It appears that your last two photos of bank 2 are not correct. Unfortunately many dealers and shops believe the ladies know nothing about cars and try to capitalize on that. This system combines 949 cc 57. The engineering firm I use are quite thorough.
It was a 30k motor that had overheated before given to him. Furthermore, all pin and journal fillets were roll-finished. The more they find wrong, the more money they can make lol. Verify the timing marks on the camshaft timing gears are in general alignment with the timing marks of the camshaft bearing cap see chart. I have a friend who is a mechanic at the local Toyota dealership and I asked him as well.
With these special thin liners it is impossible to bore the block. See Figure 3 and Figure 4. Getting back on topic, unfortunetly I wish I had the answer to your question. He told me the same thing I see here: the work isn't needed unless there's rattling coming from the engine. When the engine was running at middle speed under high load, an actuator would close the intake air control valve to increase the effective length of the intake manifold and improve intake efficiency - at medium engine speeds — due to the effect of inlet pulsations.
Of coarse, this is assuming you know where the broken piece is. This engine series also features , , one-piece cast , and a cast aluminum lower. Bore is 94 mm 3. By adopting an iridium centre electrode, ignition performance was superior to that of platinum-tipped spark plugs and durability was increased. Do you by any chance have a pic of that motor from the front.
There are two such passages for each bank for a total of four. Align the paint mark on the timing chain with the intake gear timing mark to ensure the intake gear is correctly timed to the crankshaft. Heck, I didn't see it till you mentioned it. Clean and prep the area for surgery. The cylinder block water jacket spacers prevented water flow in the middle and below the water jacket, and drew coolant above the cylinder bore for uniform temperature distribution. It has a bore and a stroke of 94 mm × 95 mm 3. This engine is new to me so I have a question that needs to be answered before I can start.
