This engine is of a non-interference design: the valves don't contact the pistons if the timing belt breaks. This engine is of a non-interference design: the valves don't contact the pistons if the timing belt breaks. For mild road tuned engines the choice is not critical but for ultimate engines and especially big valve heads the right casting numbers need to be used. In front new top mounts for the struts were used, these can be identified from a single center bolt holding the top mount. Dave Sorry to wake the Zombies but I have just had this problem and finally cracked it. The unique identifier is a series of numbers and letters that are put in a specific sequence, and the location of the digit determines what that digit designates. There are differing opinions on the best multigrade engine oil to use.
This is partly due to the design of the hydraulic tappets. In South Africa, the 1. These engines are rare among smaller North American Ford vehicles and are heavily sought after for their power output, durability, and fuel efficiency. I offer a standard 1600, a 1700 and the 1905 as well as specials up to 2. Capacity increases are also well worth considering if you want good power but without losing low end tractability.
Most other types of engine show little or no cam wear in normal use and if wear does start then it tends to accelerate exponentially leading to rapid failure. The cylinder head was equipped with hydraulic roller camshaft followers to reduce noise and help the engine to run more smoothly. And sometimes, the date code can be stamped in the wrong order, as in the example shown above. It was debuted in 1968 and sold through 1997. Accralites are recommended beyond this level although these are to special order only.
As It offered little improvement in terms of either performance or economy over the older Kent engine which was cheaper to manufacture. It was later used in the as well as the and from 1983 it was used in the. Some of them are ok with a reasonable improvement in high rpm power in exchange for a fair loss of low rpm power - others are awful and best avoided. In fact there is a design fault in the engine which means that the cam lobes on number 4 are not properly positioned relative to the lifter bores. It is simple in design and light in weight compared to earlier engines like the Pinto and Crossflow engine. When the valve seat drops out of the cylinder head, it falls into the cylinder and damages the and. It wasn't long before the engine started receiving attention from the aftermarket tuning industry, and the 1.
The problem was that the engine had been gas-flowed to the max during the design phase, so that when the engine tuners finally got their hands on them, they couldn't extract more than 110 bhp, and that sort of sealed its fate really. Those three letters refer to the revison of the Zetec s Zetec E Duratec and Sigma i think. I stand to be corrected. Under no circumstances fit larger exhaust valves and any tuning firm that does this can be safely avoided as they have no clue how to modify this engine properly. It also includes special high quality stem seals which won't go hard like the standard Ford ones and thick spring seat washers machined from steel bar which properly locate the inner and outer spring and sets the correct preload for high rpm use. It wasn't long before the engine started receiving attention from the aftermarket tuning industry, and the 1.
Accralites are recommended beyond this level although these are to special order only. In all other respects the head is the same as an early hemi head. These engines usually drop a valve seat with no warning, even if the engine has been well maintained. Date codes are located in various areas, and are normally comprised of 3 or 4 digits. Is the cost of re engining a 9 year old 1. This indicates the part was originally designed for a 1968 Mercury, and illustrates how parts crossed over from one line to another, across divisions, and the equipment provided on a particular vehicle often determined that different parts were used.
I have my own valves made and offer 43. Best suited to bigger capacity engines because this head flows so much air that a 1600 bottom end will need to rev beyond 7,500 to make use of the flow and this is pushing the limit for what the rods and pistons will stand. The standard engine only needs 7 psi 0. Replace everything, clean the brass lubrication bushes and if the head is really badly clagged up which they tend to be then remove the head and have it chemically cleaned to remove all carbon deposits from the oilways. These numbers provide a lot of information to those who are familiar with what the numbers mean. To compound the matter, Ford didn't use the best available material for the camshafts. Peak power comes in very low at 5,000 rpm or so and although the mid range torque is nice, the lack of rev range makes it pretty dull to drive.
Standard Mahle pistons will go to 10. This recess locates the inner spring. Ford Part Numbers, Casting Numbers, and Date Codes Ford Part Numbers, Casting Numbers, and Date Codes Decode Ford, Lincoln, and Mercury part numbers, casting numbers, engineering and service parts, and date codes Ford kept track of the various parts and castings in its inventory by assigning each item its own unique alphanumeric identification number. But this brings up a new question. Somewhat surprisingly, four-speed Escort Pony models achieved better mileage than five-speed cars, with upwards of 30 mpg in city driving and 40—45 mpg on the highway not uncommon.
