To replace the crankshaft front oil seal, unfasten the timing belt along with the crankshaft sprocket and thereby, removing the sensor ring and the spacer placed behind it. Slowly open the seal using a screwdriver or seal removal tool because if the housing bore or crankshaft get scratched, there will be leakage with the new seal. Remove dirt from the boer in the engine and lubricate only the outer rim of the new seal as well as the seal lip with multi-purpose grease. Utilize a seal driver to delicately seat the new seal using a hammer and ensure that the position of the seal is correct since it is being put in a fully fitting position to the original position in addition to ensuring that the spring did not get displaced during this process. Replace the components that were unbolted to gain access to the seal and start the engine for oil leaks around the front seal. To address the crankshaft rear oil seal, one has to adhere to the following processes. To replace the camshaft oil seals, the timing belt and the camshaft sprockets need to be removed, paying particular attention to determining how deep into the bores the seals should go to be inserted with help of a seal removal tool or a screwdriver wrapped in a tape to prevent scratching the bores. Scrub the bores and uniformly oil or grease the outer circumference of the new seals, the sealing lip of the seals also has to be greased. Finally before completely tightening the bolts, use a seal driver to softly strike on the seals to install it squarely and to the depth of the old one. Last of it, replace all parts that you have taken off, make sure that belt and sprockets are in alignment and also clean the area around the seals so that you are to see any leaks in the future.
