Because both Felicia 1.6 and Felicia 1.9 engines have self adjusting valves clearance by using hydraulic tappets? 😎

Try to reset the ECU first. Disconnect the battery for 1/2 hour, both negative and positive. Touch the disconnected battery cables a few seconds to discharge any capacitor remnant charge. Connect battery cables. Test drive.

I doubt it very much.

Keep us posted about the cause of oil pressure drop so that other users learn from your experience.

Isn't it obvious? It's one of those "if it ain't broke, don't fix it" situation. No play before, play after. Logic tells me to compare the new "original" part with the old one. Flange and seal.

Did you feel the diagonal movement BEFORE changing the seal? Or AFTER?

First let us establish some things. We are talking about a 1.6 l engine type AEE. Skoda Felicia MK2 started production on 1998 January 1st. Now, what do you call "an intermediate shaft" ? The camshaft? Photos would help.

@SaltySkoda Start simple. Disregard panic mode advice if the engine had good maintenance.

I agree with Wino. It could be oil starvation rather than low oil pressure. On the other hand, since the issue shows up in extreme hot weather, I would replace the thermostat and the radiator fan thermocontact wih slightly lower temperature ones (like for tropical countries Felicia). You know, back 20 years ago, when winter was winter and nobody played God with the weather, Felicia didn't need such modifications in Europe. But now... I assume the engine maintenance was OK during its life, right? PS As for the Plastigauge question, read their recommendation.

No.

The lesson that should be learned from this event is "FIRST remove negative battery cable when you work on the electrical system of the car".

Based on what test?

Hello I would like to know what problems I might face if I try to reset all adaptation values from Select -> Engine -> Basic Settings. The message after clicking Go! is rather scary. Please see photos below. I am working on a 1.4 TSI CAXA engine.

These are all flavors of Felicia special I know of. It would be nice to gather in this topic photos of each one of them and also what special characteristics they have.

In this guide you will learn how to adjust the valve clearance. The guide is aimed at the most common engine mounted on Felicia, 1.3 MPI. The procedure is similar for other engine types, but check the Service manual for specific clearance values. Prerequisites The engine must be cold and the air temperature must be below 20 C. Remove all spark plugs. Remove the valve cover. In order to be able to rotate the engine, jack up the front right wheel and shift in 4th gear. By rotating the front right wheel clockwise by hand, the crankshaft of the engine will rotate easily. Tools needed Flat screwdriver 11 mm ring wrench Feeler gauge set Torque wrench (optional) The "5" method We will apply the method known as the "5" method for reasons described below. Definition: Valve overlap - we say that the valves overlap when, for a short time, both valves (intake and exhaust) are open. This moment occurs when the exhaust stroke ends and the intake stroke begins. In terms of crankshaft angle of rotation for all Felicia 1.3 engines, the valves overlap for 20 - 39 degrees. We can assess that moment fairly precise for each cylinder by watching the movement of respective rockers. We look for the precise moment when the exhaust rocker is ending to move up and the intake rocker is starting to move down simultaneously. So let's do it! Rotate the crankshaft until: Cylinder 4 valves overlap --> Adjust valves clearance on cylinder 1 Rotate the crankshaft 180 degrees until: Cylinder 2 valves overlap --> Adjust valves clearance on cylinder 3 Rotate the crankshaft 180 degrees until: Cylinder 1 valves overlap --> Adjust valves clearance on cylinder 4 Rotate the crankshaft 180 degrees until: Cylinder 3 valves overlap --> Adjust valves clearance on cylinder 2 We see now why the method is called the "5" method. The sum of the cylinder numbers for overlapping and adjusting is always 5 (4+1, 2+3, 1+4, 3+2). The process is shown in detail in the figure below. Adjustment Insert the ring wrench over the locking nut of the rocker and unscrew it half a turn. Insert the corresponding feeler gauge between the rocker and the valve stem (see photo below). Rotate the screw with the screwdriver until the feeler gauge moves with a slight drag. Keep the screwdriver still and lock the nut with the ring wrench. Optionally torque the nut at 15 Nm with a torque wrench. Repeat the process to all eight valves. Then rotate the engine two turns and recheck all eight valves again. Assemble everything in reverse order.

I bring to your attention the subject of setting the valves clearance for Skoda Felicia. There are two methods available: one described in Skoda workshop manual and another described in Haynes manual. They are not equivalent, meaning they produce different results. So my question is: what method you find more accurate? Why? Skoda method Haynes method
